soc/intel/skylake: Fix SATA booting to OS issue

SATA device remains unrecognized if connected at Port 2.

Port control and Status register (PCS) is by default set by
hardware to the disabled state as a result of an initial
power on reset. OS read PCS register during boot causes
disabling of SATA ports and can't detect any devices.

BRANCH=none
BUG=chrome-os-partner:59335
TEST=Build and boot SKL from SATA device connected at Port 2.
