Obtain from TAMP backup register information about image authorization
status and partition id used for booting. Store this info in
environmental variables ("boot_auth" and "boot_part" correspondingly).
Image authorization supported values:
0x0 - No authentication done
0x1 - Authentication done and failed
0x2 - Authentication done and succeeded
These values are stored to TAMP backup register by Trusted Firmware-A [1].
Testing:
STM32MP> print boot_part
boot_part=1
STM32MP> print boot_auth
boot_auth=2
