[PATCH v2 3/9] drm: Rename drm_bridge_timings to drm_timings

[Fabrizio Castro <fabrizio.castro@bp.renesas.com>]

The information represented by drm_bridge_timings is also
needed by panels, therefore rename drm_bridge_timings to
drm_timings.

v1->v2:
* new patch

I have copied the license from include/drm/drm_bridge.h as that's
where the struct originally came from. What's the right SPDX license
to use in this case?
