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

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)

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.
