samus: Remove PP1800_PGOOD check
The PP1800_PGOOD pullup resistor was no-stuff on P2B boards so
the input value is floating and cannot be relied on for proper

Before P2B it was always pulled up so it was not a useful signal
to wait on anyways.
BUG=chrome-os-partner:29502
BRANCH=None
TEST=buid and boot on samus proto2b
