anx7447: USB Mux is reset when TCPM is reset
Calling tcpm_init will reset the Analogix USB Mux on port 0. I'm not
sure if this is the proper behavior but I lean towards that it's not
because there is a separate function, usb_mux_init, for resetting
the usb mux. Also, calling tcpm_init for the Parade does not reset
it's mux.
BUG=b:134829988
BRANCH=none
TEST=manual
HATCH (Port 0): The original and new stack was tested as follows:
1) Plug in dock
2) Depending on dock, plug in HDMI or DP
3) Plug TypeC power into dock
4) Verify projection on external monitor isn't lost
