phy: can-transceiver: Re-instate "mux-states" property presence check
On the Renesas Gray Hawk Single development board:
can-transceiver-phy can-phy0: /can-phy0: failed to get mux-state (0)
"mux-states" is an optional property for CAN transceivers. However,
mux_get() always prints an error message in case of an error, including
when the property is not present, confusing the user.
Fix this by re-instating the property presence check (this time using
the proper API) in a wrapper around devm_mux_state_get(). When the
multiplexer subsystem gains support for optional muxes, the wrapper can
just be removed.
In addition, propagate all real errors upstream, instead of ignoring
them.
