As the upcoming release will be based on Linux 5.10 only, remove all
kernel configuration as well as patches for Linux 5.4.
There were no targets still actively using Linux 5.4.

-Subject: loop: Report EOPNOTSUPP properly
-
-Properly plumb out EOPNOTSUPP from loop driver operations, which may
-get returned when for instance a discard operation is attempted but not
-supported by the underlying block device. Before this change, everything
-was reported in the log as an I/O error, which is scary and not
-helpful in debugging.
