    libpayload: Add usb_generic_(create|remove) functions for unrecognized devices
    It might be useful to provide a USB driver in the payload itself instead of in
    libpayload. For example there are multiple payloads being built and linked
    against the same libpayload, and they might not need or even want to have the
    same set of drivers installed.
    This change adds two new functions, usb_generic_create and usb_generic_remove,
    which behave like the usbdisk_create and usbdisk_remove functions which are
    defined for USB mass storage devices. If a USB device isn't recognized and
    claimed by one of the built in USB class drivers (currently hub, hid, and msc)
    and the create function is defined, then it will be called to give the payload
    a chance to use the device. Once it's removed, if usb_generic_remove is
    defined it will be called, effectively giving the payload notice.
    Built and booted depthcharge on Link. Built depthcharge for Daisy. Built
    a netbooting payload, called usb_poll() with those functions implemented, and
    verified that they were called and that the devices they were told about were
    reasonable and the same as what was reported by lsusb in the booted system.
