Add dts for Ariaboard Photonicat RK3568.

Working IO:
    Debug UART
    SDIO QCA9377 WiFi and Bluetooth
    M.2 E-Key PCIe WiFi and Bluetooth
    M.2 B-Key USB Modem WWAN
    Ethernet WAN Port
    MicroSD Card slot
    eMMC
    HDMI Output
    Mali GPU
    USB Type-A

Not working IO:
    Ethernet LAN Port (Lack of SGMII support)
    Power management MCU on UART4 (Driver pending)

Not working IO in MCU:
    Battery voltage sensor
    Board temperature sensor
    Hardware Power-off
    Hardware Watchdog
    Network status LED
    Real-time clock
    USB Charger voltage sensor

About onboard power management MCU:
    A heartbeat must be sent to the MCU within 60 seconds,
    otherwise the MCU will restart the system.
    When powering off, a shutdown command needs to be sent to the MCU.
    When the power button is long pressed, the MCU will send a shutdown
    command to the system. If system does not shutdown within 60 seconds,
    the power will be turned off directly.
    MCU only provides voltage for charger and battery.
    Manufacturer removed RK8xx PMIC.
