mb/google/{hatch,sarien}: Configure GPIOs using cnl_configure_pads 

This change uses cnl_configure_pads to configure GPIOs in ramstage so
that cannonlake SoC code can re-configure the GPIOs after FSP-S is
run. This is just adding a workaround until FSP-S is fixed.

BUG=b:123721147
BRANCH=None
TEST=Verified that there are no TPM IRQ timeouts in boot log on hatch.
