drm/omap: Switch the HDMI and VENC outputs to drm_bridge

The TPD12S015, OPA362 and analog and HDMI connectors are now supported
by DRM bridge drivers, and the omapdrm HDMI and VENC outputs can be
handled through the drm_bridge API. Switch the outputs to drm_bridge by
making the next bridge mandatory and removing the related
omapdrm-specific display drivers.
