powerpc/mpic: Add in-core support for cascaded MPICs
The Cell and PowerMac platforms use virtually identical cascaded-IRQ setup code, so just merge it into the core. Ideally this code would trigger automatically when an MPIC device-node specifies an "interrupts" property, perhaps even enabling MPIC_SECONDARY along the way. Unfortunately, Benjamin Herrenschmidt has had bad experiences in the past with the quality of Apple PowerMac device-trees, so to be safe we will only try to parse out an IRQ if the MPIC_SECONDARY flag is set by the caller.
