    targets/auracast_usb: Sync MCU linker script with mynewt-core
    
    The target uses a copy of nRF5340 MCU linker script from mynewt-core
    that places LC3, libsamplerate, libm and audio_usb code in RAM.
    The copy got out of date with core and the application no longer
    links (undefined static_conf_handlers) since link tables are
    missing.
    
    Regenerate the script from current mynewt-core version, which brings
    in link tables (that now also provide net core image section), NSC
    region and .noinit section, and keep only auracast specific code
    placement on top of it.
