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.
