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.

-MIME-Version: 1.0
-Content-Disposition: inline
-Content-Transfer-Encoding: 8bit

-
-Arrange the register field definitions to be grouped together, rather
-than the Armada-3700 definitions being separated from the rest of the
-definitions.
