Fix confusion in the Property arrays for the "arm11mpcore_priv"
(per-CPU devices for the ARM11MPcore CPU) and "realview_mpcore"
(realview-eb board specific device encapsulating CPU and some
extra interrupt controllers) -- the num-irq property was defined
on the wrong device and the mpcore_rirq_properties were defined
as offsets in the wrong structure. The effect was that the
realview-eb-mpcore machine would abort on startup trying to
allocate an insane amount of memory. (This bug was introduced in
the QOM conversion in commit 999e12bb.)

The trouble with doing all this as macro magic is that you end up
repeating yourself and nothing errors out saying "you fool, when
you typed the name of the object struct for the nth time you
got it wrong"...
