soc/intel/apollolake: Implement SPI flash status register read

This was a dummy implementation until now which returned -1 always. Add
    support for reading SPI flash status register (srp0).

BUG=chrome-os-partner:59267
    BRANCH=None
    TEST=Verified by enabling and disabling write-protect on reef that the
    value of SRP0 changes accordingly in status register read.
