[Xen-devel] xen-commandline document

Recently there have been several requests to add disclaimers like "only applicable if CONFIG_xyz defined" to docs/misc/xen-command-line.pandoc. As that file will be used as source for the installed file /usr/share/doc/xen/html/misc/xen-command-line.html there might be a better alternative instead
