This patchset include a couple of different
things - all related to panels.

- The callbacks are optional - so drop error if
  callback is not present.
 
- Add support for backlight in drm_panel.
  This allows us to make much simpler backlight
  support to most panels.
  The patchset include conversion of most of the
  trivial cases.

- Drop drm_connector from drm_panel.
  This change required many changes to most
  panels and many bridges and display drivers.
  This is by far the most invasive change in this patchset.

With this patchset drm_panel_(attach|detach) are nop's
but they are kept for now.

A few of these patches has been sent out before - but versioning
started again from v1 - as the most patches are new.

I have tested the panel-simple changes, and thus some
of the infrastructure changes.
The testing was done on an earlier iteration - and I ended
up submitting this as Laurent and others started to depend on it.

v2:
  This is mostly addressing comments from Laurent.
  - drop get_timings removal, we should start using it
  - do not fail in drm_panel_of_backlight() if DT is not enabled
  - updated changelogs and code comments in many places (thanks Laurent!)
  - get_modes is a mandatory callback - return -EOPNOTSUPP if not specified
  - log if backlight update fails
  - added a-b/r-bs
    o thanks to Laurent and Linus for the prompt reviews!

When "drm/panel: add backlight support" is reviewed I plan to
apply the full series to drm-misc-next.

Fixed the last bits pointed out by Laurent and pushed to drm-misc-next.
