This is a refactoring patch, no functionality is changed. It moves loader.S and galileo.ld from platform/galileo/ to cpu/x86/ directory since they seem to be more SoC-specific than platform-specific. It also renames galileo.ld to quarkX1000.ld since it can be used by any platform based on Quark X1000 SoC, not only Galileo. Furthermore, this patch also renames loader.S to bootstrap_quarkX1000.S since it is pretty much a bootstrap code to any platform based on Quark X1000 SoC.
