usb: typec: mux: do not return on EOPNOTSUPP in {mux, switch}_set

Since the typec connectors can have many muxes or switches for different
lanes (sbu, usb2, usb3) going into different modal states (usb2, usb3,
audio, debug) all of them will be called on typec_switch_set and
typec_mux_set. But not all of them will be handling the expected mode.

If one of the mux or switch will come back with EOPTNOSUPP this is no
reason to stop running through the next ones. Therefor we skip this
particular error value and continue calling the next.
