    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.
    
    TEST=Build and Boot Kunimitsu
