mb/google/dedede: Read DRAM population strap

Configure DRAM population strap GPIO according to the schematics.
Configure an internal pull-up to support the boards in which the strap
is not populated. Read the strap and pass that information to FSP for
memory initialization.

BUG=b:152275658, b:154301008
TEST=Build and boot the mainboard. Ensure that the strap information is
read as expected and passed to FSP.
