soc/intel: Consolidate FSP CAR setup and teardown code

This patch adds following changes,

- APL, CFL, DENVERTON soc's using same implementation to setup and
  teardown FSP CAR. Hence cache_as_ram_fsp.S from soc folder is
  cosolidated into one file and moved to common code CPU car folder.
- exit_car_fsp.S is from APL, DNV soc folder is clubbed into one file
  and moved to common CPU car.
- The new file apollolake/fspcar.c is addded to pass tempraminit
  parameters.

- Coffee lake Soc uses FSPT to support Intel Security features like
  BootGuard verify boot and Measured boot. Add FSP CAR support for CFL
  by programming tempraminit parameters and add FSP_T_XIP default if
  FSP_CAR is selected.

BUG= None
TEST= Build for both CFL RVP11 & RVP8 and verified for successful CAR setup.
      Build for both leafhill and harcuvar platform by selecting CONFIG_FSP_CAR
      without errors.
