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] jailhouse: Add simple debug console via the hypervisor
-
-Jailhouse allows explicitly enabled cells to write character-wise
-messages to the hypervisor debug console. Make use of this for a
-platform-agnostic boot diagnosis channel, specifically for non-root
-cells. This also comes with earlycon support.
