Merge tag 'tags/bcm2835-dt-next-2020-07-06' into devicetree/next

Maxime Ripard introduces two new clock providers into RPi4's device tree:

- The first one based on the enhancements made to clk-raspberrypi, which
  is now registered trough DT and provides control over the whole range
  of firmware based clocks.

- The second one based on the new clk-bcm2711-dvp driver, which gates
  the clocks and reset signals that feed into RPi4's HDMI0/1 blocks.
