skylake: set DISB in GEN_PMCON_A register properly
DISB (bit 23) in GEN_PMCON_A represents to MRC that DRAM training is complete. However, as a 8-bit write was being performed the bit was never being set. BUG=chrome-os-partner:43516 BRANCH=None TEST=Built and booted to kernel. Rebooted. Noted full memory training was not being peformed.
