[media] s5p-fimc: Add device tree support for FIMC-LITE device driver

This patch adds the device tree support for FIMC-LITE device
driver. The bindings include compatible property for the Exynos5
SoC series, however the actual implementation for these SoCs will
be added in a separate patch.

+Exynos4x12/Exynos5 SoC series camera host interface (FIMC-LITE)
+
+Required properties:
+
+- compatible    : should be "samsung,exynos4212-fimc" for Exynos4212 and
+                  Exynos4412 SoCs;
+- reg           : physical base address and size of the device memory mapped
+                  registers;
+- interrupts    : should contain FIMC-LITE interrupt;
+- clocks        : FIMC LITE gate clock should be specified in this property.
+- clock-names   : should contain "flite" entry.
+
+Each FIMC device should have an alias in the aliases node, in the form of
+fimc-lite<n>, where <n> is an integer specifying the IP block instance.
