**DEPENDS ON: [[graceful reboot] Add the pre_reboot_hook script execution, add the watchdog arm before the reboot](https://github.com/sonic-net/sonic-utilities/pull/3203)**
#### Why I did it
Add support for the `graceful reboot` instead of the `sysfs power cycle` to avoid filesystem corruption
### How I did it
Rename the `platform_reboot` script to the `pre_reboot_hook`.
Remove the sysfs power cycle function, from now on the Debian reboot (`/sbin/reboot`) will be executed instead of the sysfs power cycle.
#### How to verify it
1. Start watching logs by using `show log -f` and `journalctl -p debug -f`
2. Execute the `reboot` command from the switch CLI
3. Check in logs that all systemd services terminated
- Why I did it
The cable thermal sensors will be deprecated from the kernel driver. When cable host management is enabled, NOS will fetch the cable temperature from cable EEPROM, kernel driver will not provide the sysfs anymore.
- How I did it
Remove the relevant sensor form the conf files
- How to verify it
Run sonic mgmt sensor test

- Why I did it
Based on some research some products might experience an occasional IO failures in the communication between CPU and SSD because of NCQ.
There seems to be a problem between some kernel versions and some SATA controllers.
Syslog error message examples:
Error "ata1: SError: { UnrecovData Handshk }" - "failed command: WRITE FPDMA QUEUED".
Error "ata1: SError: { RecovComm HostInt PHYRdyChg CommWake 10B8B DevExch }" - "failed command: READ FPDMA QUEUED".
Some vendors already disabled NCQ on their platforms in SONiC due to similar issue:
[Arista] Disable ATA NCQ for a few products #13739 [Arista] Disable ATA NCQ for a few products
[Arista] Disable SSD NCQ on DCS-7050CX3-32S #13964 [Arista] Disable SSD NCQ on DCS-7050CX3-32S
Also there are other discussions on Debian/Ubuntu forums about similar issues and it was suggested to disable NCQ:

- How I did it
Add a kernel parameter to tell libata to disable NCQ

- Why I did it
Advance hw-mgmt service to V.7.0020.4100
Add missing thermal sensors that are supported by hw-mgmt package
Delay system health service before hw-mgmt has started on Mellanox platform in order to avoid reading some sensors before ready.
Depends on sonic-net/sonic-linux-kernel#305
- How I did it
1. Update hw mgmt version
2. Add missing sensors
3. Delay service
- How to verify it
Regression test.

Remove extra empty lines in the SN2201 pg_profile_lookup.ini to make it aligned with other platforms.
This extra empty line could confuse some test cases which need to parse this file.

- Why I did it
1. SN2201 sai profile needs to be updated according to the latest hardware.
2. In the reboot script, need to use the common symbol link of the power_cycle sysfs instead of directly accessing it due to SN2201 sysfs is different than other platforms.
3. echo 1 > $SYSFS_PWR_CYCLE will trigger the reboot immediately, the following sleep 3 and echo 0 > $SYSFS_PWR_CYCLE will never be executed, can be removed.
- How I did it
1. Replace the SN2201 sai profile with the latest one.
2. In the platform_reboot script, replace the direct sysfs path with the symbol link path.
3. Remove the redundant code from platform_reboot
- How to verify it
Perform reboot on all the Nvidia platforms, and check all can be rebooted successfully.
