[media] s5p-jpeg: Add initial device tree support for S5PV210/Exynos4210 SoCs
This patch enables the JPEG codec on S5PV210 and Exynos4210 SoCs. There are some differences in newer versions of the JPEG codec IP on SoCs like Exynos4x12 and Exynos5 series and support for them will be added in subsequent patches.

+- reg : address and length of the JPEG codec IP register set;
+- interrupts : specifies the JPEG codec IP interrupt;
+- clocks : should contain the JPEG codec IP gate clock specifier, from the
+ common clock bindings;
+- clock-names : should contain "jpeg" entry.
