usb: typec: Add wrapper for bus switch set code 



Add a wrapper that calls the set() function for various switches
associated with a port altmode.

Right now, it just wraps the existing typec_mux_set() command,
but it can be expanded to include other switches in future patches.

No functional changes introduced by this patch.
