soc/intel/common: Move CSE Lite driver functionality into romstage
The patch sets up the CSE Lite driver in the romstage instead of ramstage.
With this change, CSE Lite driver sets CSE's boot partition and triggers
CSE FW update in the romstage. The cse_fw_sync() must be called after DRAM
initialization as HMRFPO_ENABLE HECI command (which is used by
cse_fw_sync()) is expected to be executed after DRAM initialization. With
this change, it improves the cold boot time by ~154ms.
Test=Verified on JSL and TGL platforms
BUG=b:174694480
