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] staging/fsl_qbman: Calculate valid bit from MC-RR
-
-Use the management commmand response registers to determine
-the next expected valid bit when initializing a software
-portal. This avoids using the wrong valid bit in cases
-where a command was partially written but then not
-completed.
