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] dpaa2-eth: Add autoneg support
-
-For MC versions that support it, use the new DPNI link APIs, which
-allow setting/getting of advertised and supported link modes.
-
-A mapping between DPNI link modes and ethtool ones is created to
-help converting from one to the other.
