[PATCH 4.14 175/237] USB: misc: iowarrior: add support for the 100 device

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit bab5417f5f0118ce914bc5b2f8381e959e891155 upstream.

Add a new device id for the 100 devie. It has 4 interfaces like the 28
and 28L devices but a larger endpoint so more I/O pins.
