grunt family: Provide pu/pd for port 1 BC1.2
Port 1 is provided by a daughterboard. In the event that the
daughterboard is disconnected, these pins are floating. Pull them in
the appropriate direction for their logic when the board is
disconnected.
BUG=b:111942717
BRANCH=none
TEST=make -j buildall; Test startup on Careena hardware both with and
without port 1 connected to the mainboard.
