sb/intel/common/firmware: Add Intel ME/TXE firmware check
Ensure that the provided ME/TXE firmware is valid, using the
check capabilities of me_cleaner.
me_cleaner checks that the fundamental partition is available and
it has a correct signature. The checks performed by me_cleaner
aren't exhaustive, but they should find at least whether the user
has provided an empty or corrupted firmware.
me_cleaner has been tested on all the ME (6-11.6) and TXE (1-3)
firmwares available here [1], and it hasn't reported any false
positive.
