efi/arm64: efistub: remove local copy of linux_banner
The shared efistub code for ARM and arm64 contains a local copy of linux_banner, allowing it to be referenced from separate executables such as the ARM decompressor. However, this introduces a dependency on generated header files, causing unnecessary rebuilds of the stub itself and, in case of arm64, vmlinux which contains it. On arm64, the copy is not actually needed since we can reference the original symbol directly, and as it turns out, there may be better ways to deal with this for ARM as well, so let's remove it from the shared code. If it still needs to be reintroduced for ARM later, it should live under arch/arm anyway and not in shared code.
