Pull "Broadcom devicetree changes for 4.14" from Florian Fainelli:

This pull request contains Broadcom ARM-based SoCs Device Tree changes for
4.14, please pull the following:

- Eric moves the bcm2837 DT file from arm64 to arm because it created a maintenance
  problem and would have required either duplication or cross merges

- Stefan changes how the pinmuxing is defined and pushes it at the board level
  to support Raspberry Pi Zero Wireless. He then adds supports for the actual
  Raspberry Pi Zero Wireless board along with binding documentation. Stefan
  also defines a proper SMP enable-method property and binding for BCM2836
  (Raspbery Pi 2)

- Rafal describes the BCM5301X USB ports correctly in Device Tree such that
  it becomes possible to assign them to specific LED triggers (e.g: USB activity).
  He does the same thing for BCM53573 and defines default LED triggers for USB.

- Jon provides a fix for Northstar Plus which consists in correctly defining
  the "dma-coherent" property for peripherals which are DMA coherent. He also
  does a bit of re-arrangement of the USB DT nodes and finally adds USB 3 PHY
  and host controller support for NorthStar Plus

- Florian adds support for Broadcom's BCM947189ACDBMR reference board which is
  based on BCM47182/53573 and which supports external MoCA (BCM6802)

- Ray fixes the wrong UART2 base address for Cygnus

- Scott moves the v3d node in the proper unit address order and defines the correct
  UART alias for the BCM91130_entphn reference board to be UART3

- Jason adds the DT node for the Cygnus Cortex-A9 Performance Monitoring Unit

- Jonathan adds a bunch of additional peripherals to the Cygnus DTS include file:
  SDHCI, Keypad, SPI, DMA and pinmux configurations

- Raveendra adds the Cygnus OHCI and EHCI Device Tree nodes
