The nexus node remapping handling consists in handling #*-cells, *-map, *-map-mask and *-map-pass-thru properties. This is already supported by of_parse_phandle_with_args_map(). Add support for nexus node device-tree binding and the related remapping in the PWM subsystem by simply using of_parse_phandle_with_args_map() instead of of_parse_phandle_with_args().
