    PVH: support whitespace cmdline splitting
    
    For historical reasons, Xen kernel command lines have options
    separated by commas.  Every other FreeBSD platform uses whitespace;
    this is also necessary in PVH in order to support the Firecracker
    VMM.  Allow options to be separated by any combination of commas
    and whitespace.
