Marek Szyprowski 04427ec574 drm/exynos: add support for 'hdmi' clock
Mixed need to have hdmi clock enabled to properly perform power on/off
sequences, so add handling of this clock directly to the mixer driver.
Dependency between hdmi clock and mixer module has been observed on
Exynos4 based boards.

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>;
};
