drm/cma: add debugfs helpers
Add helper to display fb's which can be used directly in drm_info_list:
static struct drm_info_list foo_debugfs_list[] = {
...
{ "fb", drm_fb_cma_debugfs_show, 0 },
};
to display information about CMA fb objects, as well as a
drm_gem_cma_describe() which can be used if the driver bothers to keep
a list of CMA GEM objects.
