drm/debugfs: create debugfs late register functions

Browse Source 
Although the device-centered debugfs functions can track requests for
the addition of DRM debugfs files at any time and have them added all
at once during drm_dev_register(), they are not able to create debugfs
files for modeset components, as they are registered after the primary
and the render drm_minor are registered.

So, create a drm_debugfs_late_register() function, which is responsible
for dealing with the creation of all the debugfs files for modeset
components at once. Therefore, the functions drm_debugfs_add_file()
and drm_debugfs_add_files() can be used in late_register hooks.
