From: Carlo Caione <carlo@xxxxxxxxxxxx>
Fix pin controller documentation introducing the new compatibles for
the pinctrl drivers specific for aobus / cbus.
This is needed because we have changed the pin controller driver: we
have now a single specialized pinctrl driver / compatible for each bus
the controller is attached to, instead of one single driver dealing with
all the controllers we have on different buses.
