This patch add support for virtio dgram for the driver.
Implemented related functions for tx and rx, enqueue
and dequeue. Send packets synchronously to give sender
indication when the virtqueue is full.
Refactored virtio_transport_send_pkt_work() a little bit but
no functions changes for it.
When this feature is enabled, allocate 5 queues,
otherwise, allocate 3 queues to be compatible with
old QEMU versions.

Moving the driver-specific mmap code into a GEM object function allows
for using DRM helpers for various mmap callbacks.
The respective xen functions are being removed. The file_operations
structure fops is now being created by the helper macro

The function qxl_gem_prime_mmap() returns an error. The two callers
of gem_prime_mmap are drm_fbdev_fb_mmap() and drm_gem_dmabuf_mmap(),
which both already handle NULL-callbacks with an error code. So clear
gem_prime_mmap in qxl and remove qxl_gem_prime_mmap().

Replace all remaining implementations of struct drm_driver.gem_prime_mmap
with use drm_gem_prime_mmap(). For each affected driver, put the mmap code
into struct drm_gem_object_funcs.mmap. With the latter change in place,
create struct file_operations via DEFINE_DRM_GEM_FOPS().
