    kernel: provide i6300esb for qemu/libvirt
    
    the Intel i6300esb is QEMU's default watchdog. And unlike
    the real "Intel i6300ESB I/O Controller hub" hardware, the
    i6300esb watchdog driver works on non-x86 targets like for
    ARM (armvirt 32bit) and potentially virtual PowerPC and MIPS
    targets (if there was any).
