[PATCH v1 0/7] drm/bridge: Drop deprecated functions

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.
