honeybuns: Add C2 initialization with power button on/off
This CL refactors code required for the user facing usbc port. This
port was only being initialized at init time and therefore would not
function properly following a power button off/on.
To avoid duplicating code, the functions used to initialize this port
and control VBUS were moved to usbc_support in baseboard so they can
be common and are now guarded by a GPIO macro so this can be board
specific for variants which don't have a PPC to control on this port.
BUG=b:164157329
BRANCH=quiche
TEST=Verifed that port C2 attaches as expected following power button
off/on sequence.
