    Add SiP service to configure Arm Ethos-N NPU · 76a21174

    By default the Arm Ethos-N NPU will boot up in secure mode. In this mode
    the non-secure world cannot access the registers needed to use the NPU.
    To still allow the non-secure world to use the NPU, a SiP service has
    been added that can delegate non-secure access to the registers needed
    to use it.
    
    Only the HW_CONFIG for the Arm Juno platform has been updated to include
    the device tree for the NPU and the platform currently only loads the
    HW_CONFIG in AArch64 builds.
