[v2,0/1] bridge/ti-sn65dsi86.c: convert to atomic operations

This patch is what is left on a previous attempt to make the
ti-sn65dsi86 support DRM_BRIDGE_ATTACH_NO_CONNECTOR.

I ran into several challenges on the way:
- I never found a way to retreive bpc when the driver
  do not create the connector - and the driver needs it.
  There may be ways to change how bpc is used but as I have no access
  to HW it is not easy to change much.
- My understanding of the driver is limited so I dropped trying to
  do the proper implmentation of format negotiation
- I had made a small macro to encapsulate a few of the common functions
  in drm_bridge_funcs - but looking at it with fresh eyes told me
  this is not a good idea.

I dropped previous a-b / r-b as the driver has changed a bit since
last submission.
Especially to Kieran - sorry for letting you wait so long for almost nothing.
