soc/intel/cmn/cse: API to perform essential CSE operations post EOP

This patch creates an API that can perform essential CSE operation
after sending the late EOP command to the CSE and prior booting to OS.

Lists of operation are
- Perform global reset lock
- Put HECI1 to D0i3 and disable the HECI1 if the user selects
- Set D0I3 for all HECI devices.

BUG=b:260041679
TEST=Able to boot Google/Rex after sending CSE EOP late.
