The use of load and unload hooks is deprecated. DRM drivers should
use drm_dev_alloc|drm_dev_init and drm_dev_register for initialization
and publishing.

Sparse emitted the following warning:
../drivers/staging/vboxvideo/vbox_fb.c:173:27: warning: incorrect type in assignment (different address spaces)
../drivers/staging/vboxvideo/vbox_fb.c:173:27: expected char [noderef] <asn:2>*screen_base
../drivers/staging/vboxvideo/vbox_fb.c:173:27: got void *virtual
The vbox_bo buffer object kernel mapping is handled by a call
to ttm_bo_kmap() prior to the assignment of bo->kmap.virtual to
info->screen_base of type char __iomem*.
Casting bo->kmap.virtual to char __iomem* in this assignment fixes
the warning.
vboxvideo: Fix address space of expression removal sparse warning
Sparse emitted the following warning:
../drivers/staging/vboxvideo/vbox_main.c:64:25: warning: cast removes address space of expression
vbox->vbva_buffers iomapping is handled by calling vbox_accel_init()
from vbox_hw_init().
__force attribute is used in assignment to vbva to fix the warning.

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.
drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

This commit adds the vboxvideo drm/kms driver for the virtual graphics
card used in Virtual Box virtual machines to drivers/staging.
Why drivers/staging? This driver is already being patched into the kernel
by several distros, thus it is good to get this driver upstream soon, so
that work on the driver can be easily shared.
At the same time we want to take our time to get this driver properly
cleaned up (mainly converted to the new atomic modesetting APIs) before
submitting it as a normal driver under drivers/gpu/drm, putting this
driver in staging for now allows both.
Note this driver has already been significantly cleaned up, when I started
working on this the files under /usr/src/vboxguest/vboxvideo as installed
by Virtual Box 5.1.18 Guest Additions had a total linecount of 52681
lines. The version in this commit has 4874 lines.
