soc/intel/common: Add downgrade support for CSE Firmware
Add downgrade support for CSE RW firmware.
When CSE FW is downgraded, CSE may get into data compatibility issues.
To avoid such issues, coreboot sends DATA CLEAR HECI command to CSE to
clear CSE run time data on proactive basis during a downgrade and
when CSE indicates a data mismatch error through GET_BOOT_PARTITION_INFO.
BUG=b:144894771
