Over time we have accumulated some deprecated functions etc. in drm_bridge. This patch-set starts to move over to the atomic variants and deletes what is not used anymore.
There was only one user of the non-atomic drm_bridge_chain functions in parade-ps8640 - migrate it to the atomic variants and delete the non-atomic drm_bridge_chain functions.
There was only one user of drm_bridge_chain_mode_fixup in mediatk. The use in the mediatek driver was wrong and with the single user gone we could also delete this function.
Added a few todo items.
Next step is to migrate the easy bridge drivers to use the atomic variants of drm_bridge_funcs operations. The easy ones are the drivers wihtout mode_set or mode_fixup. I have something typed up already, but wanted feedback on this patchset before sending out additional patches.
