drivers/intel/fsp2_0: add FSP TempRamInit & TempRamExit API support
FSP v2.0 Specification adds APIs TempRamInit & TempRamExit for
Cache-As-Ram initialization and teardown. Add fsp2_0 driver
support for TempRamInit & TempRamExit APIs.
Verified on Intel Leaf Hill CRB and confirmed that Cache-As-Ram
is correctly set up and torn down using the FSP v2.0 APIs
without coreboot implementation of CAR init/teardown.
