puff: Change default VCCST_PG_OD to low.
The EDS expects VCCST_PWRGD to remain low until VCCST and VDDQ are
stable and within specification. From a fresh EC boot, this seems
unlikely so default to low.
BRANCH=none
BUG=b:148042540
TEST=make buildall; puff cold boot succeeds consistently on a dut where
it previously failed consistently
