drm: drm_debugfs.h self-contained While removing drmP.h from drm/radeon a few files ended up including drm_debugfs.h as the first file. This failed build due to missing dependencies in drm_debugfs.h.

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

drm/gpuvm: rename struct drm_gpuva_manager to struct drm_gpuvm Rename struct drm_gpuva_manager to struct drm_gpuvm including corresponding functions. This way the GPUVA manager's structures align very well with the documentation of VM_BIND [1] and VM_BIND locking [2]. It also provides a better foundation for the naming of data structures and functions introduced for implementing a common dma-resv per GPU-VM including tracking of external and evicted objects in subsequent patches.

Drivers can add DRM debugfs files to a device-managed list and, during drm_dev_register(), all added files will be created at once.
