soc/intel/cmn/cse: Store ISH firmware version into CBMEM

The patch stores the ISH in the CBMEM table. It verifies CSE has been
updated by comparing previous and current CSE versions. If it has, the
patch updates the previous CSE version with the current CSE version. It
then updates the CBMEM table with the current ISH version.

BUG=b:273661726
TEST=The current and old CSE and ISH versions are verified on the
google/nissa during cold and warm reboots.

Additionally, version updates are verified by a debug patch that
purposely updated the stored cse version.
