ide: delete filenames/versions from comments

Delete filenames/versions from comments.

I'm leaving decisions about adding DRV_VERSION defines and MODULE_VERSION()-s
to maintainers of the respective drivers.

While at it:

* Remove unused VERSION define from ide.c.

* Remove unused/stale DRV_VERSION define from au1xxx-ide.c.
