mb/google/dedede: Remove pad termination for RAM_STRAP_4
The stuffed resistor straps are weaker compared to the internal pull-up.
This can cause the GPIO to read '1' always. Remove the internal pull-up.
Also read the GPIO only on the boards where the board version is
populated.
BUG=b:154301008
TEST=Build and boot the mainboard.
