Jean-Jacques Hiblot 35b8b92c85 drivers: mux: mmio-based syscon mux controller
This adds a driver for mmio-based syscon multiplexers controlled by
bitfields in a syscon register range.
This is heavily based on the linux mmio-mux driver.

The mux framework is a minimalistic subsystem that handles multiplexer
controllers. It provides the same API as Linux and mux drivers should
be portable with a minimum effort.

MMIO register bitfield-controlled Multiplexer controller.
The driver builds multiplexer controllers for bitfields in a syscon
register. For N bit wide bitfields, there will be 2^N possible
multiplexer states.
