[PATCH v2 2/5] drm/vmwgfx: Add debugfs entries for various ttm resource managers

[Zack Rusin]

From: Zack Rusin <zackr at vmware.com>

Use the newly added TTM's ability to automatically create debugfs entries
for specified placements. This creates debugfs files that can be read to
get information about various TTM resource managers which are used by
vmwgfx.
