samus_pd: add internal pull-up to EC_IN_RW
Add internal pull-up to EC_IN_RW to match changes made in DVT.
Doesn't affect earlier boards because a hardware bug prevented
us from reading the correct state anyway.
BUG=none
BRANCH=samus
TEST=make -j buildall
Test on re-worked samus board with DVT changes. Tested PD MCU
can read the correct state of the gpio.
