Subject: [PATCH 2/4] media: dt-bindings: samsung,exynos4212-fimc-lite: convert to dtschema

Convert the Samsung Exynos SoC series camera host interface (FIMC-LITE)
bindings to DT schema.  Changes during conversion - adjust to existing
DTS and Linux driver: add iommus and power-domains.

-		  "samsung,exynos5250-fimc-lite" for Exynos5250 compatible
-		   devices;
-- 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
