mb/google/zork: Configure all pads in ramstage for trembyle reference
This change configures all missing pads in ramstage for trembyle
reference. This ensures that the state of all pads is set correctly
for the payload/OS. Also, all the pads for the platform are configured
in baseboard gpio table in ramstage to ensure that variants can
override any pads if required.
