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 Tx shaping support
-
-Add support in sysfs for controlling DPNI Tx shaping
-parameters: rate limit (in Mbps) and max burst size (in bytes).
-The settings are per port.
-
-TODO: See how to integrate Tx shaping support using
-standard Linux tools (ethtool)
