guybrush: Fix ANX7451 driver
Correct i2c address of ANX7451 on guybrush.
Do not attempt to read or write mux in Z1 since mux is not powered.
The only required init step is to disable ultra low power. So init can
be removed if ultra low power is always set inside set.
Prevent disabling both DP and USB at the same time since this causes mux
to fail.
BUG=b:184907521, b:184908498
TEST=Display port works on Guybrush B2
BRANCH=None
