media: dt-bindings: media: samsung,s5pv210-jpeg: convert to dtschema 



Convert the Samsung SoC JPEG codec bindings to DT schema.

The original bindings were quite old and incomplete, so change during
conversion:
1. Add typical (already used) properties like iommus and power domains.
2. Document samsung,exynos4212-jpeg compatible (already used in DTS and
   driver).
3. List clocks per each variant.

Samsung S5P/Exynos SoC series JPEG codec



Required properties:



- compatible	: should be one of:

		  "samsung,s5pv210-jpeg", "samsung,exynos4210-jpeg",

		  "samsung,exynos3250-jpeg", "samsung,exynos5420-jpeg",

		  "samsung,exynos5433-jpeg";

- reg		: address and length of the JPEG codec IP register set;

- interrupts	: specifies the JPEG codec IP interrupt;

- clock-names   : should contain:

		   - "jpeg" for the core gate clock,

		   - "sclk" for the special clock (optional).

- clocks	: should contain the clock specifier and clock ID list

		  matching entries in the clock-names property; from

		  the common clock bindings.
