Currently the mux_control_get implementation only deals with getting
mux controllers on DT platforms. This commit renames the current
implementation to of_mux_control_get to reflect this and makes
mux_control_get a wrapper around of_mux_control_get.
This is a preparation patch for adding support for getting muxes on
non DT platforms.
