kernel: delete Linux 5.4 config and patches

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: [PATCH] sdk_dpaa: ls1043a errata: memory related fixes
-
-Avoid a crash by verifying the allocation return status.
-
-Use the standard API for determining the page order needed for
-allocating Jumbo sized skbs.
-
-Explicitly remove the old skb outside the w/a, for both successful and
-unsuccessful realignments. Make sure the old skb's memory isn't leaked.
