drm/simple-kms: Deprecate simple-kms helpers
Deprecate simple-encoder and simple-display-pipe helpers in favor of
regular atomic helpers. Remove the related documentation. Add TODO
item for converting the remaining drivers.
These helpers have been deprecated for years and many drivers have
been updated to not use them. Still there are a few left and we
occasionally receive new drivers build upon them. Marking them as
deprecated will hopefully resolve these problems. The TODO items
should be easy enough for getting new voluteers started on DRM driver
development.
