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.
