Convert the Exynos Mixer bindings to DT schema format.
The conversion includes also updates to the bindings, matching the
current DTS and Linux driver:
1. Add clocks required on Exynos4210 and Exynos4212 types of Mixer.
2. Add second memory range on Exynos4210 and Exynos4212.
3. Add interconnects, iommus and power-domains.

-Device-Tree bindings for mixer driver
-
-Required properties:
-- compatible: value should be one of the following:
- 1) "samsung,exynos5-mixer" <DEPRECATED>
- 2) "samsung,exynos4210-mixer"
- 3) "samsung,exynos4212-mixer"
- 4) "samsung,exynos5250-mixer"
- 5) "samsung,exynos5420-mixer"
-
-- reg: physical base address of the mixer and length of memory mapped
- region.
-- interrupts: interrupt number to the cpu.
-- clocks: list of clock IDs from SoC clock driver.
- a) mixer: Gate of Mixer IP bus clock.
- b) sclk_hdmi: HDMI Special clock, one of the two possible inputs of
- mixer mux.
- c) hdmi: Gate of HDMI IP bus clock, needed together with sclk_hdmi.
-
-Example:
-
- mixer {
- compatible = "samsung,exynos5250-mixer";
- reg = <0x14450000 0x10000>;
- interrupts = <0 94 0>;
- };
