soc/intel/common: Add check before sending HMRFPO_ENABLE command
This patch adds a check to determine if the CSE's current operation mode
is ME_HFS1_COM_SECOVER_MEI_MSG or not before sending HMRFPO_ENABLE
command to CSE. If CSE is already in the ME_HFS1_COM_SECOVER_MEI_MSG,
coreboot skips sending HMRFPO_ENABLE command to CSE to unlock the CSE RW
partition.
TEST=Verify sending HMRFPO_ENABLE command on Brya system.
