powerpc: Add support for CoreInt delivery of interrupts on MPIC
CoreInt provides a mechansim to deliver the IRQ vector directly into the core on an interrupt (via the SPR EPR) rather than having to go IACK on the PIC. This is suppose to provide an improvment in interrupt latency by reducing the time to get the IRQ vector. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
