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.
