Drivers should not have a dependency on NR_IRQS. Doing so may break with
SPARSE_IRQ enabled. As there are no in kernel users of the pl061 which
have multiple instances with their interrupts combined to a single parent
interrupt, remove this functionality. If this capability is needed later,
it could be supported more cleanly by just using a devicetree property.

Convert the pl061 irq_chip code to use the generic irq chip code.
This has the side effect of using 32-bit accesses rather than 8-bit
accesses to interrupt registers. The h/w TRM and testing seem to indicate
this is fine.
