Subject: [PATCH v6 0/5] drm: minimize drmP.h dependencies

Updated patchset, with merged patches removed, new patches added.

> From the original mail:

        - drmP.h is now stripped down to include files
          and forward declarations.
        - All header files in include/drm/ no longer include drmP.h.

The series was made on top of drm-misc-next:
f1a2a540c86441016ce3dff6590b7a09080871de ("video/hdmi: Add an enum for HDMI packet types")

Build tested using arm and x86, ia64, alpha, sparc32, sparc64
Included staging/vboxvideo in the build test - which revealed
the build issues Daniel had identifed

This series include fixes to i915 as it looks in drm-misc.
This series also include fixes to stagin/vboxvideo, which I
expect to be committet to drm-misc due to the final patch
(drmP.h removal from drm_modeset_helper.h) depending on this patch.

Daniel - thanks for being paitent and applying this piecemal.

        Sam
v6:
- include fixes to vboxvideo (Daniel)

- Rebased on top of drm-misc-next

v2:
