soc/intel/skylake: restore MCHBAR and DMIBAR programming
Program MCHBAR, DMIBAR, EPBAR, EDRAMBAR and GDXCBAR.
Also program the PAM registers. The system agent was being
programmed in romstage during pre-console initialization, after
moving to C_ENVIRONMENT bootblock this was missing, restoring
the same.
