drm: debugfs: provide infrastructure to dump a DRM GPU VA space

Browse source

This commit adds a function to dump a DRM GPU VA space and a macro for
drivers to register the struct drm_info_list 'gpuvas' entry.

Most likely, most drivers might maintain one DRM GPU VA space per struct
drm_file, but there might also be drivers not having a fixed relation
between DRM GPU VA spaces and a DRM core infrastructure, hence we need the
indirection via the driver iterating it's maintained DRM GPU VA spaces.
