drm/virtio: Use new drm_fb_helper functions
Use the newly created wrapper drm_fb_helper functions instead of calling core fbdev functions directly. They also simplify the fb_info creation. v3: - Don't touch remove_conflicting_framebuffers v2: - add missing header for virtgpu_fb.c Cc: David Airlie <airlied@linux.ie> Cc: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
