drm/panel: drop drm_device from drm_panel
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.

- editorial correction in changelog (Laurent)
