There were some issues with the current Linuxboot Makefiles.
- multithreaded compilation didn't work, because some prerequisites
were missing
- initramfs wasn't added for x86 qemu boot.
- riscv support was incomplete
It began with separate patches, but resulted in a clean up patch, that
is hard to separate. The most important changes are the following:
- Instead of phony targets, actual files are now used as prerequisites
- riscv can now be used as target
- initramfs works now also for x86
- instead of querying the most recent version from the internet, I set a
known working version (because I tested it) that can be customized
and/or upgraded in the future. The reasons:
- querying the version from the internet requires a constant
connection to the internet even after linux kernel is already
build (aka subsequent builds).
- one usually wants to use a known working version, but optionally
still have the posibillity to choose a custom one. This patch
introduces this possibility in its most simple form.
- I removed as much ifeq statements as possible and moved that
responsibility to Kconfig, because they tend to make the
Makefile less readable.

Clean and refactor the structure of the LinuxBoot payload integration,
to make it more modular and readable. The kernel and initramfs should
handled in separated makefiles.
tested with:
- qemu-i440fx (x86, x86_64)
- cavium CN8100 (arm64)

The extra firmware is not part of upstream kernel.
Fixes build error if the firmware is not present.
