soc/intel/cse: Check PSR bit before issuing PSR backup command

Get PSR bit state using MKHI_FWCAPS_GET_FW_FEATURE_STATE HECI command
Use this bit info to check if SKU supports PSR and consequently issue
PSR_HECI_FW_DOWNGRADE_BACKUP command for PSR data backup during
downgrade.

BUG=b:273207144
TEST=build CB image and boot on google/rex board. Check for
"PSR is supported in this SKU" message in coreboot logs to confirm
that PSR bit is set in SKU
