[PATCH v3 4/6] hw/openrisc/openrisc_sim: Increase max_cpus to 4

[Stafford Horne <shorne@gmail.com>]

Now that we no longer have a limit of 2 CPUs due to fixing the
IRQ routing issues we can increase the max.  Here we increase
the limit to 4, we could go higher, but currently OMPIC has a
limit of 4, so we align with that.
