Yeah, this seems a reasonable alternative to me. Pushing the pinmux_map
construction down to individual pinctrl driver, who can interpret 'mux'
property best, will relieve the pinctrl core from understanding the
property for different cases, so that we can even save the property
'mux-unit' I asked for. And doing so somehow aligns with non-dt case,
where the pinmux_map is constructed by individual pinctrl driver too
(with help from PINMUX_MAP_* macros in board file).
