mb/google/sarien: Disable unused GPIOs
These 4 GPIOs are being disconnected in the next board so use the
board ID to configure these pins as not connected to ensure
they do not cause leakage.
Also remove the ACPI _PTS S5 code that was configuring the GPIOs.
This does mean they will cause small leakage in S5 on existing boards,
but it will not affect the new boards.
BUG=b:132393441
TEST=boot on sarien with fake board ID and ensure that coreboot
configures these pads as expected.
