As the upcoming release will be based on Linux 5.10 only, remove all

There were no targets still actively using Linux 5.4.

-Subject: [PATCH] cgroup/bfq: revert bfq.weight symlink change
-
-There's some discussion on how to do this the best, and Tejun prefers
-that BFQ just create the file itself instead of having cgroups support
-a symlink feature.
-
-Hence revert commit 54b7b868e826 and 19e9da9e86c4 for 5.2, and this
-can be done properly for 5.3.
