pinctrl: add generic board-level pinctrl driver using mux framework
Many boards use on-board mux chips (often controlled by GPIOs from an I2C
expander) to switch shared signals between peripherals.
Add a generic pinctrl driver built on top of the mux framework to
centralize mux handling and avoid probe ordering issues. Keep board-level
routing out of individual drivers and supports boot-time only mux
selection.
Ensure correct probe ordering, especially when the GPIO expander is probed
later.
