mb/google/hatch: Configure GPIO pad for non-inversion
This implementation configures GPIO (GPP_A21, GPP_C21, GPP_D16)
pad in non-inversion mode i.e Rx PAD state is not inverted as
it is sent from GPIO to IOAPIC.
BUG=b:123315212
TEST=Tested for below:
-> Verify touchpad is working fine.
-> TPM init is successful and boot with fixed boot media.
