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.
