ARM: dts: Add DISP1 power domain for exynos5420
The DISP1 power domain on Exynos5420 SoC includes the FIMD1, MIXER and HDMI modules. Add a device node for this power domain and mark these modules as consumer of the DISP1 power domain. When a power domain is powered on and off, the input clocks of the devices attached to it are reparented. So a reference to the input and parent clocks of the devices are needed to manage that.
