cros: Add information about booting Chrome OS on x86
Recent versions of Chrome OS do not have a kernel in the root disk, to
save space.
With the improvements to the 'zboot' command it is fairly easy to load
the kernel from the raw partition. Add instructions on how to do this.

When booting Chrome OS images the command line is stored separately
