virtio_gpu_mode_dumb_destroy() is the same as drm_gem_dumb_destroy()
which is the drm_driver.dumb_destroy default, so no need to set it.

drm_debugfs_cleanup() now removes all minor->debugfs_list entries

Before commit a325725633c2 ("drm: Lobotomize set_busid nonsense for !pci
drivers"), several DRM drivers for platform devices used to expose an
explicit "drm_driver.set_busid" callback, invariably backed by
drm_platform_set_busid().
Commit a325725633c2 removed drm_platform_set_busid(), along with the
referring .set_busid field initializations. This was justified because
interchangeable functionality had been implemented in drm_dev_alloc() /
drm_dev_init(), which DRM_IOCTL_SET_VERSION would rely on going forward.
However, commit a325725633c2 also removed drm_virtio_set_busid(), for
which the same consolidation was not appropriate: this .set_busid callback
had been implemented with drm_pci_set_busid(), and not
drm_platform_set_busid(). The error regressed Xorg/xserver on QEMU's
"virtio-vga" card; the drmGetBusid() function from libdrm would no longer
return stable PCI identifiers like "pci:0000:00:02.0", but rather unstable
platform ones like "virtio0".
Reinstate drm_virtio_set_busid() with judicious use of

We already have a fallback in place to fill out the unique from
dev->unique, which is set to something reasonable in drm_dev_alloc.
Which means we only need to have a special set_busid for pci devices,
to be able to care the backwards compat code for drm 1.1 around, which
libdrm still needs.
While developing and testing this patch things blew up in really
interesting ways, and the code is rather confusing in naming things
between the kernel code, ioctl #defines and libdrm. For the next brave
dragon slayer, document all this madness properly in the userspace
interface section of gpu.tmpl.
v2: Make drm_dev_set_unique static and update kerneldoc.
v3: Entire rewrite, plus document what's going on for posterity in the
gpu docbook uapi section.
v4: Drop accidental amdgpu hunk (Emil).
v5: Drop accidental omapdrm vblank counter change (Emil).
v6: Rebase on top of the sphinx conversion.

This allows us to ditch a ton of ugly #ifdefs from a bunch of drm modeset
drivers.
v2: Make the dummy function actually return a sane value, spotted by
Ville.
v3: Because the patch is still in limbo there's no more drivers to
convert, noticed by Emil.
v4: Rebase once more, because hooray. I'll just go ahead an apply this
one later on to drm-misc.

This patch adds a kms driver for the virtio gpu. The xorg modesetting
driver can handle the device just fine, the framebuffer for fbcon is
there too.
Qemu patches for the host side are under review currently.
The pci version of the device comes in two variants: with and without
vga compatibility. The former has a extra memory bar for the vga
framebuffer, the later is a pure virtio device. The only concern for
this driver is that in the virtio-vga case we have to kick out the
firmware framebuffer.
Initial revision has only 2d support, 3d (virgl) support requires
some more work on the qemu side and will be added later.
