This fixes the auto-magic detection of LEDS_CLASS by fixing the case where nouveau would be built-in and the LEDS_CLASS would be built as as module.

Removing the build-time dependency on DRM_KMS_FB_HELPER means we can now build with CONFIG_FB disabled or as a loadable module, leading to a link error: ERROR: "remove_conflicting_framebuffers" [drivers/gpu/drm/virtio/virtio-gpu.ko] undefined! There is no need to call remove_conflicting_framebuffers() if CONFIG_FB is disabled, or if the virtio-gpu driver is built-in and CONFIG_FB=m, as

The proper fix would have been to select LEDS_CLASS but this can lead to a circular dependency, as found out by Arnd. This patch implements Arnd's suggestion instead, at the cost of some auto-magic for a fringe feature.

This series cleans up duplicated code for replacing firmware FB driver with proper DRI driver and adds handover support to Tegra driver. The last patch is here because it uses new semantics of remove_conflicting_framebuffers() from this series. This can be considered independently, though. --- Micha?

vDPA supports the possibility to use user VA in the iotlb messages. So, let's add support for user VA in vringh to use it in the vDPA simulators.
