Fetch boot arguments from the next boot image by reading it from uboot environment variables.
What I did
In current scenario, during warm-reboot for arm64, boot arguments are fetched from device tree of the current image. This causes an issue during upgrade/downgrade with warm-reboot.
How I did it
With the change, boot arguments for arm64 is fetched from uboot environment variables. The logic relies on creation of
"sonic_bootargs" environment variable to fetch the right boot argument.
How to verify it
Tested by sonic to sonic install followed by warm-reboot.
