[PATCH v3 4/4] arm64: dts: allwinner: h616: Add BigTreeTech Pi support

[Martin Botka]

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

Changes in V2:
    - Add UART alongside aliases and chosen for it
    - Add model string
    - Enable IR receiver
    - Enable SPI0 for ADXL345 connector
Changes in V3:
    - Add missing semicolons
    - Add pinctrl for SPI0
