mb/google/sarien: Adjust GPD3 pin termination 

Internal pull up need to be enabled for GPD3 as power button pin for
PCH according cannonlake pch EDS vol1 table 17-1. Without that pin will
stay floating and hook up XDP can cause system shutdown as power buttone
event will trigger.

BUG=N/A
TEST=Hook up XDP on sarien platform, able to boot up into OS and stay
at power up state.
