    linux-firmware: add Intel CPU-integrated GPU (iGPU) firmware
    
    On latest Intel x86 CPUs, DMC firmware is required for the iGPU to reach
    its lowest power states. If the driver cannot load it, it will print a
    warning and unnecessarily make the iGPU draw a bit more power when idle.
    
    GUC firmware (various "offload" mechanisms that deal with scheduling GPU
    workloads) and HUC firmware (required for accelerated media codec
    operations for HEVC/H.265) are probably more niche, but could also
    provde useful for some - for example, when building an
    Intel/OpenWrt-based security camera.
