Merge tag 'imx-dt64-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/dt64

The Freescale arm64 device tree updates for 4.8:
 - Update address-cells and reg properties of cpu nodes, considering
   MPIDR_EL1[63:32] bits are not used for CPUs identification on ls1043a
   and ls2080a
 - Adds the cache nodes and next-level-cache property for ls1043a and
   ls2080a to get cacheinfo work on these platforms
 - Add dma-coherent for ls1043a PCI nodes to utilize the hardware
   capability on data coherency
 - Add dis_rxdet_inp3_quirk property for USB3 device to disable rx
   detection in P3 PHY mode
