drm/msm/mdp5: fix cursor-related warnings



commit c491a0c7 upstream.

Since f35a2a99 ("drm/encoder: make encoder control functions
optional") drm_mode_config_validate would print warnings if both cursor
plane and cursor functions are provided. Restore separate set of
drm_crtc_funcs to be used if separate cursor plane is provided.
