PCI: Kill off set_irq_flags() usage

Browse source 
set_irq_flags is ARM-specific with custom flags which have genirq
equivalents.  Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags.  The translation of flags is as follows:

  IRQF_VALID -> !IRQ_NOREQUEST
  IRQF_PROBE -> !IRQ_NOPROBE
  IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in .map()
functions, and we can simply remove the set_irq_flags calls.  Some users
also modify IRQ_NOPROBE, and this has been maintained although it is not
clear that is really needed.  There appears to be a great deal of blind
copy and paste of this code.
