Subject: USB: xhci: Add broken streams quirk for Frescologic device id 1009

From: Hans de Goede <hdegoede@redhat.com>

commit d95815ba6a0f287213118c136e64d8c56daeaeab upstream.

I got one of these cards for testing uas with, it seems that with streams
it dma-s all over the place, corrupting memory. On my first tests it
managed to dma over the BIOS of the motherboard somehow and completely
bricked it.

Tests on another motherboard show that it does work with streams disabled.
