drm/todo: Add entry for fb funcs related cleanups 



We're doing a great job for really simple drivers right now, but still
a lot of boilerplate for the bigger ones.

drm_framebuffer_funcs and drm_mode_config_funcs.fb_create cleanup

-----------------------------------------------------------------



A lot more drivers could be switched over to the drm_gem_framebuffer helpers.

Various hold-ups:



- Need to switch over to the generic dirty tracking code using

  drm_atomic_helper_dirtyfb first (e.g. qxl).



- Need to switch to drm_fbdev_generic_setup(), otherwise a lot of the custom fb

  setup code can't be deleted.



- Many drivers wrap drm_gem_fb_create() only to check for valid formats. For

  atomic drivers we could check for valid formats by calling

  drm_plane_check_pixel_format() against all planes, and pass if any plane

  supports the format. For non-atomic that's not possible since like the format

  list for the primary plane is fake and we'd therefor reject valid formats.



- Many drivers subclass drm_framebuffer, we'd need a embedding compatible

  version of the varios drm_gem_fb_create functions. Maybe called

  drm_gem_fb_create/_with_dirty/_with_funcs as needed.
