    at91: explicitly set CONFIG_USB_SUPPORT for sam9x subtarget
    
    The at91 target sets
    
      FEATURES:=usb usbgadget ...
    
    in the target Makefile, which sets CONFIG_USB_SUPPORT=y in the
    .config file for both subtargets.
    
    However, when building with all kmods, the build fails with the
    following error message:
    
      ERROR: module [...]/drivers/bluetooth/btusb.ko is missing.
    
    It appears that only a part of the bluetooth files are compiled.
    The package depends @USB_SUPPORT.
    
    This can be easily healed by adding CONFIG_USB_SUPPORT=y to the
    sam9x subtarget configuration. Before the 4.14->5.4 bump, the
    same was also set in the target's config-4.14 file along with
    several other USB config options that are not reimplemented.
    
    Still, it remains a mystery to me why setting the same symbol
    via target kernel config creates a different result than the
    feature setting the same symbol in target-metadata.pl.
