honeybuns: Add board level USB_PD_CONNECT hooks
This CL moves the board specific parts of USB_PD_CONNECT hook to
board.c file as there are different GPIOs that must be changed between
quiche/gingerbread.
For Gingerbread, the USB Hubs are held in reset until there is a usbc
attach event.
quiche/baklava don't require USB hub resets to be controlled, but do
have a separate GPIO indicator the MST hub.
BUG=b:206059703
BRANCH=quiche
TEST=verified GPIO signal levels for signals affected by this CL on
quiche and gingerbread.
