commented out for sarien. It is only used for testing and currently
it is useful to have an image that works on both board versions.

Currently CoffeeLake FSP is incorrectly modifying GPIO pad configuration
if specific UPD variables are not set as it expects.
This affects the display-related SOC pads with the following UPD variables:
UINT8 DdiPortBHpd; // GPP_E13
UINT8 DdiPortCHpd; // GPP_E14
UINT8 DdiPortDHpd; // GPP_E15
UINT8 DdiPortFHpd; // GPP_E16
UINT8 DdiPortBDdc; // GPP_E18/GPP_E19
UINT8 DdiPortCDdc; // GPP_E20/GPP_E21
UINT8 DdiPortDDdc; // GPP_E22/GPP_E23
UINT8 DdiPortFDdc; // GPP_H16/GPP_H17
Until FSP is fixed to not touch the pad configuration this workaround
will reprogram the GPIO settings after FSP-S step so they are correct
when the OS attempts to use them.
This was found in CoffeLake FSP Gold release:
https://github.com/IntelFsp/FSP/tree/master/CoffeeLakeFspBinPkg
As well as the current top-of-tree for the FSP sources.
