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: net: sfp: avoid tx-fault with Nokia GPON module
-
-The Nokia GPON module can hold tx-fault active while it is initialising
-which can take up to 60s. Avoid this causing the module to be declared
-faulty after the SFP MSA defined non-cooled module timeout.
