[PATCH v3 06/12] drm: remove include of drmP.h from bridge/dw_hdmi.h

[Sam Ravnborg <sam@ravnborg.org>]

drmP.h is an relic from the days when there was a single header file.
To enable the removal of drmP.h from all users drop include
of drmP.h from bridge/dw_hdmi.h.

A few files relied on the file included in drmP.h - add explicit
include statements or forward declarations to these files.
Build tested with arm and x86.

v2:
- prefer forward declarations when possible (Laurent Pinchart)
- sort include files (Laurent Pinchart)
