dedede: Add board_vbus_presence_change()
Dedede doesn't have a dedicated interrupt for ACOK, however we can use
the charger or TCPC to inform us when AC is OK through other means.
This commit uses the board_vbus_presence_change() trigger to trigger
the HOOK_AC_CHANGE hook.
BUG=b:154113446,b:154113465
BRANCH=None
TEST=Build and flash waddledoo, plug in AC, verify that "AC on" prints
are seen. Unplug AC, verify that "AC off" prints are seen.
