usb: pi3usb9281: Allow flexible chip configurations
Previously we supported using a single pi3usb9281 chip, or using two
chips on the same i2c bus behind a mux. Now that we need to support a
third configuration of multiple chips on different busses, it makes
sense to be able to configure the configuration freely at the board
level.
BUG=chrome-os-partner:40920
TEST=Manual on samus_pd. Plug USB charger, verify detection is correct
on both charge ports.
