[PATCH v5 4/4] arm64: dts: allwinner: h616: Add BigTreeTech Pi support

[Martin Botka]

From: Martin Botka <martin at biqu3d.com>

The BigTreeTech Pi is an H616 based board based on CB1.
Just in Rpi format board.

It features the same internals as BTT CB1 but adds:
    - Fan port
    - IR receiver
    - ADXL345 Accelerometer connector via SPI
    - 24V DC power supply via terminal plugs
    - USB to CAN module connector (The actual USB to CAN happens on the external module)

List of currently working things is same as BTT CB1 but also:
    - IR receiver
    - ADXL345 connector
