Why I did it
When Supervisor card is rebooted by using PMON API, it takes about 90 seconds to trigger the shutdown in down path. At this time linecards have been up. This delays linecards database initialization which is trying to PING/PONG the database-chassis. To address this issue, we modified the NDK to use the system call with "sudo reboot" when the request is from PMON API on Supervisor case. The NDK version is 22.9.20 and greater. This new NDK requires this modifcaiton of platform_reboot to work with.

How I did it
Modify the platform_reboot In Supervisor not to reboot all IMMs since it has been done in the function reboot() in module.py. Also handle the reboot-cause.txt for on the Supervisor when the reboot is request from PMON API.
Modify the Nokia platform specific platform_reboot in linecard to disable all SPFs.
This PR works with NDK version 22.9.20 and above

These changes, in conjunction with NDK version >= 22.9.17 address the thermal logging issues discussed at Nokia-ION/ndk#27. While the changes contained at this PR do not require coupling to NDK version >= 22.9.17, thermal logging enhancements will not be available without updated NDK >= 22.9.17. Thus, coupling with NDK >=22.9.17 is preferred and recommended.
Why I did it
To address thermal logging deficiencies.

How I did it
The following changes are included:
Threshold configuration values are provided in the associated device data .json files. There is also a change included to better handle the condition where an SFP module read fails.
Modify the module.py reboot to support reboot linecard from Supervisor
- Modify reboot to call _reboot_imm for single IMM card reboot
- Add log to the ndk_cmd to log the operation of "reboot-linecard" and "shutdown/satrtup the sfm"
Add new nokia_cmd set command and modify show ndk-status output
- Add a new function reboot_imm() to nokia_common.py to support reboot a single IMM slot from CPM
- Added new command: nokia_cmd set reboot-linecard <slot> [forece] for CPM
- Append a new column "RebootStatus" at the end of output of "nokia_cmd show ndk-status"
- Provide ability for IMM to disable all transceiver module TX at reboot time
- Remove defunct xcvr-resync service

sonic-mgmt xoff test was failing for [100g,120km]. Needed to update total headroom pool size when 100G line card is used as T2 uplink.
This size was calculated assuming 100g is used for downlink so cable length was 2km whereas it can also be used for uplink (cable length - 120km). so we need to do calculation based on 120km not 2km. Although it will be some wastage for 2km scenario but it should cover both cases.
Why I did it
Update the platform_reboot of Nokia Platform IXR-7250E-36x400G to displays the correct reboot-cause history when reboot from supervisor card.

How I did it
Modify the platform_reboot script to copy the correct reboo-cause.txt file from NDK to the /host/reboot-cause directory at the down cycle when the reboot is issued from Supervisor (for both reboot right after install a new image and normal reboot)

Verified on line card on T2 chassis
Why I did it
When reboot the chassis by issuing "sudo reboot" on Supervisor card. The internal midplane communication xe0 should be shutdown to avoid double reboot on the linecard.
Added a udev link rule to disable the autoneg on AMD xgbe port Xe0 and Xe1 and make the setting in sync with the peer Broadcom greyhound ports.
How I did it
Modify the Nokia-7250IXRE specific reboot script on the Supervisor card to shutdown the internal interface xe0. Also move reboot linecard code to the top of the script to make sure the notification has been send to Linecard before shutdown the xe0 interface.
Introduced a new rule 80-net-by-driver.link to disable the autoneg on the AMD size. This change requires the latest NDK which contains the change to set the autoneg on the xe0 and xe1 port on the Greyhound.

Why I did it
On DNX (J2/J2c/J2c+) platforms, Single Path Nexthops and ECMp Nexthop resources(FECs) are shared. BRCM SAI do not have partition of this resource, and hence more single path Nexthop entries, causes ECMP programming to fail in scaled setup.
How I did it
Broadcom provided SAI changes to reserve resources for single path nexthop entries(More details in CSP: https://brcmsemiconductor-csm.wolkenservicedesk.com/wolken-support/allcases/request-details?requestId=CS00012251649).
Along with SAI changes, they provided configurable Macro/flag to reserve NON_ECMP entries.
This PR is to add that flag in various sai.profile files wherever applicable.
PS: We are reserving 3072 single path Nexthop entries on each Linecard. Calculation is as follows.
Max Slots per chassis: 8
Max No of Ports(each LC): 64
MyIP/Subnet Entries per port: 4(v4/v6)
Nbr Entries Per port: 2(v4/v6)
Total Non_ECMP Count: 8x64x(4+2) = 3072
How to verify it
Without this change, the ECMP group count will be shown as Max_count in 'crm show resources all' command, and with this change the ECMP group count will be decreased by 24(3072/128).
Added midplane_subnet in chassisdb.conf for interfaces-config.sh to create midplane interface in multi-asic namespaces.

#### Why I did it
Add platform_asic file to each platform folder in sonic-device-data package. The file content will be used as the ground truth of mapping from PLATFORM_STRING to switch ASIC family.
One use case of the mapping is to prevent installing a wrong image, which targets for other ASIC platforms. For example, currently we have several ONIE images naming as sonic-*.bin, it's easy to mistakenly install the wrong image. With this mapping built into image, we could fetch the ONIE platform string, and figure out which ASIC it is using, and check we are installing the correct image.
After this PR merged, each platform vendor has to add one mandatory text file `device/PLATFORM_VENDOR/PLATFORM_STRING/platform_asic`, with the content of the platform's switch ASIC family.
I will update https://github.com/Azure/SONiC/wiki/Porting-Guide after this PR is merged.
You can get a list of the ASIC platforms by `ls -b platform | cat`. Currently the options are
```
barefoot
broadcom
cavium
centec
centec-arm64
generic
innovium
marvell
