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 628/660] net: sfp: allow fault processing to transition to
- other states
-
-Add the next state to sfp_sm_fault() so that it can branch to other
-states. This will be necessary to improve the initialisation path.
