Rabin Vincent 01727e61f0 plat-nomadik: implement safe switch sequence for Alt-C ... Setting pinmux alternative C for a GPIO pin is actually not so easy since it ivolves setting value "1" in two registers, and since the combined result will take effect for intermediate values (01 or 10) this will cause glitches while you wrote one register but have not yet written the other. This patch implements a series of kludges including an optional machine-specific callback to avoid glitches when changing pin mux mode to alternative C.
