[PATCHv5 10/14] drm/msm: Switch to universal plane API's

[Matt Roper <matthew.d.roper@xxxxxxxxx>]

Use drm_universal_plane_init() and drm_crtc_init_with_planes() rather
than the legacy drm_plane_init() / drm_crtc_init().  This will ensure
that the proper primary plane is registered with the DRM (and eventually
exposed to userspace in future patches).
