    ppc/pnv: Make PSI device types not user creatable
    
    QEMU aborts with -device pnv-psi-POWER8:
    
    $ qemu-system-ppc64 -device pnv-psi-POWER8
    qemu-system-ppc64: hw/intc/xics.c:605: ics_realize: Assertion
    `ics->xics' failed.
    Aborted (core dumped)
    
    The Processor Service Interface Controller is an internal device.
    It should only be instantiated by the chip, which takes care of
    configuring the link required by the ICS object in the case of
    POWER8. It doesn't make sense for a user to specify it on the
    command line.
    
    Note that the PSI model for POWER8 was added 3 yrs ago but the
    devices weren't available on the command line because of a bug
    that was fixed by recent commit 2f35254aa0 ("pnv/psi: Correct
    the pnv-psi* devices not to be sysbus devices").
    
    Fixes: 54f59d786c ("ppc/pnv: Add cut down PSI bridge model and hookup 
external interrupt")
