mb/google/poppy/variants/nautilus: Add internal pull-up for USB2_OC2#

Nautilus-WiFi board doesn't have external pull-up on USB2_OC2# route, then
abnormal over-current is asserted on USB type-A port.
It causes USB type-A port to be blocked, so we need this internal pull-up.

BUG=b:111578984
BRANCH=poppy
TEST=Verified over-current not triggered abnormally on basic sku board
