PCI: Kill off set_irq_flags() usage
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.
