soc/intel/cannonlake: Configure GPIOs again after FSP-S is done
FSP-S is currently configuring GPIOs that it should not. This results
in issues where mainboard devices don't behave as expected e.g. host
unable to receive TPM interrupts as the pad for the interrupt is
re-configured as something else.
Until FSP-S is fixed, this change adds a workaround by reconfiguring
GPIOs after FSP-S is run.
All mainboards need to call cnl_configure_pads instead of
gpio_configure_pads so that SoC code can maintain a reference to the
GPIO table and use that to re-configure GPIOs after FSP-S is run.
BUG=b:123721147
BRANCH=None
TEST=Verified that there are no TPM IRQ timeouts in boot log on hatch.
