mux: gpio: add mux controller driver for gpio based multiplexers
The driver builds a single multiplexer controller using a number of gpio pins. For N pins, there will be 2^N possible multiplexer states. The GPIO pins can be connected (by the hardware) to several multiplexers, which in that case will be operated in parallel. Reviewed-by:Jonathan Cameron <jic23@kernel.org> Signed-off-by:
