Subject: [PATCH v2 0/3] spi: pca2xx: Prepare for and enable MSI support

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

  spi: pxa2xx: Factor out handle_bad_msg
  spi: pxa2xx: Prepare for edge-triggered interrupts
  spi: pca2xx-pci: Allow MSI
