soc/intel/cmd/block: Implement an API to get firmware partition details
This patch retrieves details of a specified firmware partition table.
The information retrieved includes the current firmware version and
other information about the firmware partition. The patch communicates
with the ME using the HECI command to acquire this information.
BUG=b:273661726
Test=Verified the changes for ISH partition on nissa board.
