The PCI GART table initialization code treats the GART table mapping
unconditionally as a kernel virtual address.
But it could be in the framebuffer, for example, and thus we're
dealing with a PCI MEM space ioremap() cookie. Treating that as a
virtual address is illegal and will crash some system types (such as
sparc64 where the ioremap() return value is actually a physical I/O
address).
So access the area correctly, using gart_info->gart_table_location as
our guide.

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.
