Scott W told me that me that the IPIC doesn't have the concept of EOI ack. It
just has IRQ masks.

I'm not familiar with the differences between IPIC and MPIC. What is this
patch not needed
set_irq_chained_handler overwrites MPIC's handle_irq function
(handle_fasteoi_irq) thus MPIC never gets eoi event from the
cascaded IRQ. This situation hangs MPIC on MPC8568E.
Patch adds flow level "end" handler to the MPIC, and QEIC calls
it when QEIC's interrupt processing finished.
