This adds some initial pinctrl support. I don't want to go the
way of adding full fledged pinctrl support, but still we will
need some instance which parses the devicetree for pinctrl
setup. The following does not parse the pinctrl devicetree
setup into internal data structures, but instead only calls
the pinmux driver with the devicetree node containing the
setup for a device. Turning this into register values is
completely up the pinmux driver then. The device core
will automatically call the pinctrl default setup before
probing a device so that we normally do not have to add
pinctrl code to device drivers.
