sm5803: Add trigger for board_vbus_present_change
Some boards don't have a direct interrupt indicating ACOK, but the
charger IC can provide this notification via its VBUS interrupt. This
commit adds a lightweight trigger which calls
board_vbus_presence_change() whenever the charger IC gets a VBUS
interrupt. The default implementation does nothing, but a board may
override it to make it useful.
BUG=b:154113465
BRANCH=None
TEST=Build and flash on waddledee, verify that "AC on" prints are
emitted when a charger is plugged into C0. Verify that "AC off" is
seen when the charger is unplugged.
