drm/bridge: drop drmP.h usage

Drop use of the deprecated drmP.h header file.

While touching the list of include files:
- Divide include files in blocks of linux/* drm/* etc.
- Sort individual blocks of include files
- Remove duplicated header file

v2:
- Be consistent in the order of the include blocks (Laurent)
