soc/intel/common/basecode: Implement CSE update flow
The following changes are done in this patch: 1. Get the CSE partition info containing version of CSE RW using GET_BOOT_PARTITION_INFO HECI command 2. Get the me_rw.version from the currently selected RW slot. 3. If the versions from the above 2 locations don't match start the update - If CSE's current boot partition is not RO, then * Set the CSE's next boot partition to RO using SET_BOOT_PARTITION HECI command. * Send global reset command to reset the system. - Enable HMRFPO (Host ME Region Flash Protection Override) operation mode using HMRFPO_ENABLE HECI command - Erase and Copy the CBFS CSE RW to CSE RW partition - Set the CSE's next boot partition to RW using SET_BOOT_PARTITION HECI command - Trigger global reset - The system should boot with the updated CSE RW partition.
TEST=Verified basic update flows on hatch and helios. BUG=b:111330995
