    tcl/board/orange_pi_zero_3: Add Orange Pi Zero 3 board
    
    The Orange Pi Zero 3 is an SBC that uses an Allwinner H618
    SoC. As such, JTAG support is fully available, however the
    SoC multiplexes JTAG function with UART1 and microSD.
    Unfortunately Xunlong has used UART1 for the Wifi-BT
    chip, leaving JTAG accessible only via the microSD using
    a microSD breakout board (for example).

    target: add support for Allwinner H618 SoC
    
    The Allwinner H618 is an updated H616 but appears functionally
    equivalent. It is used in small boards such as Orange Pi Zero 3.
