soc/intel/skylake: Add FSP CAR support for kabylake

Kabylake RVP11 uses FSPT to support Intel security features like
bootguard verify boot and measured boot.

This patch add FSP CAR support for kabylake by programming tempraminit
parameters in fspcar.c and also add FSP_T_XIP default if FSP_CAR is
selected in order to relocate FSPT binary while adding it in CBFS so that
it can be executed in place.

BUG=None
TEST=Build and Boot to UEFI payload on kabylake RVP11 board and verified
     for successful FSP CAR setup.
