{driver, mb, soc}: Store fw versions in CMOS memory for cold boot

During a cold reboot, the CBMEM memory resets and loses the stored
firmware versions. This causes the firmware versions to be fetched again
from the CSE, which increases the boot time by about 200 ms. This patch
stores a backup of the firmware version in CMOS and updates the CBMEM
memory during a cold reboot.

This patch also removes structure members that are no longer needed
after a CMOS backup.

BUG=b:280722061
Test=Verified the changes on nissa board.
