usb: typec: mux: Allow the mux handles to be requested with fwnode

Browse Source 
Introducing fwnode_typec_switch_get() and
fwnode_typec_mux_get() functions that work just like
typec_switch_get() and typec_mux_get() but they take struct
fwnode_handle as the first parameter instead of struct
device.
