Add max_segment argument to drm_prime_pages_to_sg(). When set pass it
through to the __sg_alloc_table_from_pages() call, otherwise use
SCATTERLIST_MAX_SEGMENT.
Also add max_segment field to gem objects and pass it to
drm_prime_pages_to_sg() calls in drivers and helpers.

When initializing gem objects call virtio_max_dma_size() to figure the
scatter list limit. Needed to make virtio-gpu work properly with SEV.

qemu 5.0 introduces a new qxl hardware revision 5. Unlike revision 4
(and below) the device doesn't switch back into vga compatibility mode
when someone touches the vga ports. So we don't have to reserve the
vga ports any more to avoid that happening.

of using ttm_bo_{reserve,unreserve}.

Use drm_gem_reservation_object_wait() in virtio_gpu_wait_ioctl().
This also makes the ioctl run lockless.
v5: handle lookup failure.
v2: use reservation_object_test_signaled_rcu for VIRTGPU_WAIT_NOWAIT.

Thin wrapper around virtio_gpu_object_create(),
but calling that directly works equally well.

No need to do the reservation dance,
we can just wait on the fence directly.
