These are various changes added in preparation for cursor planes: - Add a pipe_cursor block for 8x96 in mdp5_cfg. - Add a new pipe CAP called MDP_PIPE_CAP_CURSOR. Use this to ensure we assign a cursor SSPP for a drm_plane with type DRM_PLANE_TYPE_CURSOR. - Update mdp5_ctl_blend_mask/ext_blend_mask funcs to incorporate cursor SSPPs. - In mdp5_ctl_blend, iterate through MAX_STAGES instead of stage_cnt, we need to do this because we can now have empty stages in between. - In mdp5_crtc_atomic_check, make sure that the cursor plane has the highest zorder, and stage the cursor plane to the maximum stage # present on the HW. - Create drm_crtc_funcs that doesn't try to implement cursors using the older LM cursor HW. - Pass drm_plane_type in mdp5_plane_init instead of a bool telling whether plane is primary or not.
