This enhances the pca2xx driver's interrupt handler with support for
edge-triggered interrupts and makes use of that for PCI-hosted variants,
like the Intel Quark SoC.

Changes in v3:
- removed already applied patch "Factor out handle_bad_msg"
- avoid inner looping by making the hardware retrigger on "forgotten"
  IRQ sources
- added acked/reviewed tags

Changes in v2:
- factored out handle_bad_msg (Andy)
- reordered code in patch 3, avoiding unneeded pci_free_irq_vectors (Andy)
