Subject: [PATCH v1 2/2] arm64: dts: meson-axg: add support for JetHome JetHub D2 (j200)

JetHome Jethub D2 is a home automation controller with the following
features:
  - DIN Rail Mounting
  - Amlogic S905X3 (ARM Cortex-A55) quad-core
  - micro-HDMI video out
  - 4GB LPDDR4
  - 32GB eMMC flash
  - 1 x USB 2.0
  - 1 x 10/100/1000Mbps ethernet
  - two module slots for radio/wire interface cards
  - 2 x gpio LEDS
  - 1 x 1-Wire
  - 1 x RS-485
  - 3 x dry contact digital GPIO inputs
  - 2 x relay GPIO outputs
  - DC 9-36V power source with battery UPS on board option
