drm: exynos: moved exynos drm hdmi device registration to drm driver
This patch moved the exynos-drm-hdmi platform device registration to the drm
driver. When DT is enabled, platform devices needs to be registered within the
driver code. This patch fits the requirement of both DT and Non DT based drm
drivers.
