[PATCH v2 4/4] arm64: dts: mediatek: add Genio 520-EVK board

[Louis-Alexis Eyraud]

Add devicetree for the basic hardware enablement of the Genio 520-EVK
board, based on MT8371 SoC.

MT8371 SoC is a variant of MT8189 SoC with the following differences:
  - Arm Cortex-A78 CPU core maximum frequency (2.2 Ghz for MT8371, 3 Ghz
  for MT8189).
  - Arm Mali G57 MC2 GPU core maximum frequency (880 Mhz for MT8371, 1.1
  Ghz for MT8189)
  - one ISP engine instead of two
MT8371 hardware register maps are identical to MT8189.

The Genio 520-EVK has following features:
  - MT8371 SoC
  - MT6365 PMIC
  - MT6319 Buck IC
  - MT6375 Charger IC
  - 8GB LPDDR5 RAM
  - 64GB eMMC 5.1
  - 128GB UFS
  - 20V DC Jack
  - USB Type-C Power Adapter
  - Micro SD card slot
  - Push Button x 4 (Power, Reset, Download and Home Key)
  - LED x 3 (System Power, Reset, DC-IN Power)
  - USB Type-C Connector (USB 3.2) x 2
  - USB Type-C Connector (USB 2.0) x 1
  - 3.5mm Earphone Jack x 1 (with Microphone Input)
  - 3.5mm Line Out Audio Jack x 1
  - Analog Microphone x 1
  - Digital Microphone x 2
  - Gigabit Ethernet with RJ45 connector
  - DP x 1 (Mode over USB Type-C)
  - LVDS port x 1
  - eDP port x 1
  - UART x2 with serial-to-usb converters and USB Type-C connectors
  - UART Port x 2 on Pin Header
  - M.2 Slot x 2
  - I2C Capacitive Touch Pad
  - 4-Lane DSI x 1
  - 4-Data Lane CSI x 2
  - I2S Pin header
  - 40-Pin 2.54mm Pin Header x 1
  - CAN Bus x 1 (RS232 Connector)
