Convert Samsung Exynos5250/5420 SoC Display Port Controller bindings to DT schema with a change: add power-domains, already used in DTS. This Display Port controller is actually variant of Analogix Display Port bridge, however new DT Schema does not reference analogix,dp.yaml, because of incompatibilities in the driver. The analogix,dp.yaml expects two ports, input and output, but Linux Exynos DP DRM driver and DTS use only one port: output.
