Replace the use of drm_plane_helper_check_update() with
drm_plane_helper_check_state() since we have a plane state.
I don't see any actual users of drm_simple_kms_helper yet, so
no actual plane clipping bugs to fix.

drm_plane_helper_check_update() needs to account for the plane rotation
for correct clipping/scaling calculations. Do so.
There was an earlier attempt [1] to add this into
intel_check_primary_plane() but I requested that it'd be put into the
helper instead. An updated patch never materialized AFAICS, so I went
ahead and cooked one up myself.
v2: Deal with new drm_plane_helper_check_update() callers

Provides helper functions for drivers that have a simple display
pipeline. Plane, crtc and encoder are collapsed into one entity.
Changes since v4:
- Remove drm_connector_register() call
- Forgot to assign pipe->connector
Changes since v3:
- (struct drm_simple_display_pipe *)->funcs should be const
Changes since v2:
- Drop Kconfig knob DRM_KMS_HELPER
- Expand documentation
Changes since v1:
- Add DOC header and add to gpu.tmpl
- Fix docs: @funcs is optional, "negative error code",
"This hook is optional."
- Add checks to drm_simple_kms_plane_atomic_check()
