{driver, soc/intel/cmn/cse}: Refactor ISH FW Version implementation
This patch uses the CSE firmware specific data to store Intel
ISH firmware related information. Sending an ISH partition version
information command on every boot cycle would impact the overall boot
performance.
This information is used by the auto-test framework to ensure the ISH
firmware update is proper for in-field devices.
BUG=b:285405031
TEST=Able to build and boot google/rex. Verified ISH FW version is
getting displayed across warm resets without impacting the boot time.
