It might have been better to have the pinctrl properties optional, as there
might be boards without the image sensor attached and FIMC could still be
used in memory-to-memory mode, as Marek pointed out. But it seems too late
now to change that. The binding defines the pinctrl properties as required
(Documentation/devicetree/bindings/media/samsung-fimc.txt) and we need to
keep them in dtses.
