PATCH 1/1 arm64: enable more compressed Image formats

Plumb up Makefile arguments for the already supported formats in the kbuild
system: lz4, bzip2, lzma, and lzo.

Note that just as with Image.gz, these images are not self-decompressing and the booting firmware still needs to handle decompression before launching the kernel image.

No conceptual issues with this, but it breaks my build:

arch/arm64/Makefile:61: *** mixed implicit and normal rules: deprecated syntax arch/arm64/Makefile:61: *** mixed implicit and normal rules: deprecated syntax arch/arm64/Makefile:61: *** mixed implicit and normal rules: deprecated syntax arch/arm64/Makefile:61: *** mixed implicit and normal rules: deprecated syntax make[1]: *** No rule to make target 'Image.gz', needed by 'all'. Stop. make[1]: *** Waiting for unfinished jobs....
make: *** [sub-make] Error 2

I hear some people run auto-builders nowaways that might spot this ;)
