mambo: Enable multicore configurations
mambo: Enable multicore configurations

This enables multicore configurations in mambo.  You can change the
number of cores in mambo by changing the line:

    mconfig cpus CPUS 1

To do this, we need to sanitise the PIR that mambo sets and fixup the
ibm,ppc-interrupt-server#s properties.
