genirq: Expand generic show_interrupts()
Some archs want to print extra information for certain irq_chips which
is per irq and not per chip. Allow them to provide a chip callback to
print the chip name and the extra information.
PowerPC wants to print the LEVEL/EDGE type information. Make it configurable.
