soc/intel/skylake: use postcar stage for fsp 2.0

Utilize the postcar stage for tearing down CAR and initializing
the MTRRs once ram is up. This flow is consistent with apollolake
and allows CAR_GLOBAL variables to be directly accessed and no
need for migrating CAR_GLOBAL variables as romstage doesn't
run with and without CAR being available.
