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: verify and resize headroom
- alignment
-
-If the skb's headroom isn't aligned to 16 bytes, reallocate the entire
-skb and resize its headroom to priv->tx_headroom. Update the pointers
-to the network and transport headers accordingly.
