Subject: [PATCH] drm/panic: use `///` for private items too

`///` should still be used for private items [1]. Some of the items in
this file do so already, so do it for a few other clear candidates in
the file.

Not sure if you would consider it a fix, but please feel free to add Fixes: etc.
if so. Thanks!
