Changes in v2:
* Removed pl330 and srab dma-coherent entries due to concerns that they
were invalid
Add dma-coherent to the relevant DT entries, and add USB3 support
Jon Mason (3):
ARM: dts: NSP: Add dma-coherent to relevant DT entries
ARM: dts: NSP: Rearrage USB entries
ARM: dts: NSP: Add USB3 and USB3 PHY to NSP
