The panel drivers used drm_panel.drm for two purposes:
1) Argument to drm_mode_duplicate()
2) drm->dev was used in error messages
The first usage is replaced with drm_connector.dev
- drm_connector is already connected to a drm_device
and we have a valid connector
The second usage is replaced with drm_panel.dev
- this makes drivers more consistent in their dev argument
used for dev_err() and friends
With these replacements there are no more uses of drm_panel.drm,
so it is removed from struct drm_panel.
With this change drm_panel_attach() and drm_panel_detach()
no longer have any use as they are empty functions.
v2:
- editorial correction in changelog (Laurent)

Today the bridge creates the drm_connector, but that is planned
to be moved to the display drivers.
To facilitate this, update drm_panel_funcs.get_modes() to
take drm_connector as an argument.
All panel drivers implementing get_modes() are updated.
v2:
- drop accidental change (Laurent)
- update docs for get_modes (Laurent)

Add a type field to the drm_panel structure to report the panel type,
using DRM_MODE_CONNECTOR_* macros (the values that make sense are LVDS,
eDP, DSI and DPI). This will be used to initialise the corresponding
connector type.
Update all panel drivers accordingly. The panel-simple driver only
specifies the type for the known to be LVDS panels, while all other
panels are left as unknown and will be converted on a case-by-case
basis as they all need to be carefully reviewed.

Instead of requiring all drivers to set the dev and funcs fields of
drm_panel manually after calling drm_panel_init(), pass the data as
arguments to the function. This simplifies the panel drivers, and will
help future refactoring when adding new arguments to drm_panel_init().
The panel drivers have been updated with the following Coccinelle
semantic patch, with manual inspection to verify that no call to
drm_panel_init() with a single argument still exists.

expression panel;
expression device;
identifier ops;

Drop use of the deprecated drmP.h header file.
While touching the list of include files:
- Divide include files in blocks of linux/* video/* drm/* etc.
Be consistent in the order of the blocks
- Sort individual blocks of include files

Remove all drm_panel_detach() calls from all panel drivers and update
the kerneldoc for drm_panel_detach().
Setting the connector and drm to NULL when the DRM panel device is going
away hardly serves any purpose. Usually the whole memory structure is
freed right after the remove call. However, calling the detach function
from the master DRM device, and setting the connector pointer to NULL,
has the logic of marking the panel again as available for another DRM
master to attach. The usual situation would be the same DRM master
device binding again.

Use backlight_enable/disable helpers instead of changing
the property and calling backlight_update_status for cleaner
and simpler code and also to avoid repetitions.
