Only UMs drivers use DRM's core AGP code and ioctls. Mark the icotls
as legacy. Add the _legacy_ infix to all AGP functions. Move the
declarations to the public and internal legacy header files. The agp
field in struct drm_device is now located in the structure's legacy
section. Adapt drivers to the changes.
AGP code now depends on CONFIG_DRM_LEGACY.

Drop use of the deprecated drmP.h header.
While touching the files divide include files in blocks
and sort the files alphabetically.
v2:
- Replace all uses of DRM_WAIT_ON() with VIA_WAIT_ON()
and thus avoiding to pull in drm_os_linux.h
v3:
- DRM_WAIT_ON replacement moved to earlier patch (Emil)

The DRM_READ, DRM_WRITE macros comes from the deprecated drm_os_linux.h
header file. Remove their use to remove this dependency.
Replace the use of the macros with static inline variants.
v4:
- Use a more standard via_write8_mask() function (Emil)
v3:
- Use static inline functions, rather than macros (Emil)
- Use dedicated mask variants for byte access (Emil)

And replace the drm_core_ prefix with drm_legacy_ since really, this
isn't core stuff.
Also drop drm_core_dropmap since it's unused.
v2: Fix up i810.ko fully which somehow slipped through.

I cannot see a need to provide a DRM_ version of ARRAY_SIZE(), only used
in a few places. I suspect its usage has been spread by copy & paste
rather than anything else.
Let's just remove it for plain ARRAY_SIZE().

Checking directly for the right capability is simpler. Also this rids
us of a few places that use DRM_CURRENTPID.

Remove redundant DRM UAPI header #inclusions from drivers/gpu/.
Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and
drm_sarea.h). They are now #included via drmP.h and drm_crtc.h via a preceding
patch.
Without this patch and the patch to make include the UAPI headers from the core
headers, after the UAPI split, the DRM C sources cannot find these UAPI headers
because the DRM code relies on specific -I flags to make #include "..." work
on headers in include/drm/ - but that does not work after the UAPI split without
adding more -I flags.

With the current screwed but its ABI, ioctls for the drm, Linus pointed out that we could allow userspace to specify the allocation size, but we pass it to the driver which then uses it blindly to store a struct. Now if userspace specifies the allocation size as smaller than the driver needs, the driver can possibly overwrite memory.
This patch restructures the driver ioctls so we store the structure size we are expecting, and make sure we allocate at least that size. The copy from/to userspace are still restricted to the size the user specifies, this allows ioctl structs to grow on both sides of the equation.
Up until now we didn't really use the DRM_IOCTL defines in the kernel, so this cleans them up and adds them for nouveau.
v2:
fix nouveau pushbuf arg (thanks to Ben for pointing it out)

With the coming of kernel based modesetting and the memory manager stuff,
the everything in one directory approach was getting very ugly and
starting to be unmanageable.
This restructures the drm along the lines of other kernel components.
It creates a drivers/gpu/drm directory and moves the hw drivers into
subdirectores. It moves the includes into an include/drm, and
sets up the unifdef for the userspace headers we should be exporting.
