Subject: gpu: host1x: Clean up debugfs on removal
Git-commit: 44156eee91ba6f027afbfd6a39016c0e7e31c8e9
Patch-mainline: v5.5-rc1
References: bsc#1152472

The debugfs files created for host1x are never removed, causing these
files to be left dangling in debugfs. This results in a crash when any
of these files are accessed after the host1x driver has been removed,
as well as a failure to create the debugfs entries when they are added
again on driver probe.
