As we are going to add support for the Allwinner DE2 Mixer in sun4i-drm driver, we will finally have two types of layers. Each layer is bound to a drm_plane that is CRTC-specific, so we create them when initializing CRTC (calling sun4i_layers_init, which will be generalized in next patch). The drm_plane's will be used when creating CRTC, but the CRTC initialization code do not care other properties of the layer, so we let the sun4i_layers_init function return drm_plane's only. As we have no need to trace the layers after the CRTC is properly created, we drop the layers pointer in sun4i_crtc struct. Doing this uncouples the CRTC code from the type of layer (the sun4i_layers_init function name is still hardcoded and will be changed in the next patch), so that we can finally gain support for the mixer in DE2, which has different layers.
