From: Thierry Reding <treding at nvidia.com>

This series of patches gets rid of the host1x drm_bus implementation in
Tegra DRM. It introduces a drm_dev_set_unique() function that is used to
statically set the unique name of the device, thereby eliminating the
last remaining need for drm_bus.

There are also a couple of patches to update documentation and explain
how other drivers can use the same mechanism to get rid of the drm_bus
midlayer. This should be easy to do for both drm_platform and drm_usb,
but drm_pci is still a special case, though Daniel Vetter has plans on
how to get rid of drm_bus for PCI drivers too.

Compared to v2 I've left out the conversion to the component helpers
because nobody could be bothered to look at the patches. As a result
I've decided to stick with the existing implementation that has proven
to work equally well.
