This updates the existing omapdrm DSI code, so that it uses
common drm_mipi_dsi API and drm_panel.
The patchset has been tested with Droid 4 using Linux console, X.org and
Weston. The patchset is based on Laurent Pinchartl's patch series [0]
and removes the last custom panel driver, so quite a few cleanups on the
omapdrm codebase were possible.
[0] [PATCH v7 00/54] drm/omap: Replace custom display drivers with drm_bridge and drm_panel

I pushed this patchset into the following branch:
git://git.kernel.org/pub/scm/linux/kernel/git/sre/linux-n900.git omapdrm/bridge/devel-with-dsi
The previous version of this patchset has been sent quite some time ago.
This version has been rebased and required cleaning up most of the
hacks. I do not have a detailed changelog, but quite a few things
changed. I decided against doing anything special for the DT change
(adding DSI channel number), since only 3 devices are affected. It is
quite likely, that all developers of those devices update DT together
with kernel for those devices. My suggestion is to merge the first two
patches ASAP and backport to stable, since it does not affect old
kernels and the change is rather small.
