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.

-- 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.
