Feat/coreboot linuxboot

[AtomicFS]

I think I messed something up. The coreboot with linuxboot does not build.

Running go-task build:coreboot-linuxboot fails with:

E: Could not add [inputs/bzImage, 17823199 bytes (17405 KB)@0x0]; too big?
E: Failed to add 'inputs/bzImage' into ROM image.
E: Failed while operating on 'COREBOOT' region!
E: The image will be left unmodified.
make: *** [Makefile.inc:1110: build/coreboot.pre] Error 1

@MDr164 need some help

UPDATE

This PR adds new more complex example on firmware-action usage.

To keep it somewhat clean, I moved the existing example into separate directory.

I suppose this is due to the coreboot config setting a rather small ROM area but given that QEMU is not bound to having a fixed firmware size you can simply raise the value in the coreboot config.

@MDr164 btw, this should now work.
