ARM: driver updates for 3.13

Updates of SoC-near drivers and other driver updates that makes more sense to
take through our tree. In this case it's involved:

- Some Davinci driver updates that has required corresponding platform code
  changes (gpio mostly)
- CCI bindings and a few driver updates
- Marvell mvebu patches for PCI MSI support (could have gone through the PCI
  tree for this release, but they were acked by Bjorn for 3.12 so we kept them
  through arm-soc).
- Marvell dove switch-over to DT-based PCIe configuration
- Misc updates for Samsung platform dmaengine drivers
