Guybrush: Set both FRS signals as GPIO
Both PPCs require the FRS signal be set as soon as we've enabled FRS
swapping. Use the board FRS enable function to set these through the
TCPC ioexpander.
BRANCH=None
BUG=b:183586640
TEST=on guybrush, attach WooHubs to C0 and C1, and ensure FRS can
complete successfully
