Subject: drm/virtio: batch resource creation
Git-commit: 2e819a119d96aa6cfb69f36a7299d9aa690c9dea
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

Move virtio_gpu_notify() to higher-level functions for
virtio_gpu_cmd_create_resource(), virtio_gpu_cmd_resource_create_3d()
and virtio_gpu_cmd_resource_attach_backing().

virtio_gpu_object_create() will batch commands and notify only once when
creating a resource.
