xhci: Add broken-streams quirk for Fresco Logic FL1000G xhci controllers

commit 7f5c4d631aed243ca89c6673427954210b1628ec upstream.

Streams do not work reliabe on Fresco Logic FL1000G xhci controllers,
trying to use them results in errors like this:

21:37:33 kernel: xhci_hcd 0000:04:00.0: ERROR Transfer event for disabled endpoint or incorrect stream ring
21:37:33 kernel: xhci_hcd 0000:04:00.0: @00000000368b3570 9067b000 00000000 05000000 01078001
21:37:33 kernel: xhci_hcd 0000:04:00.0: ERROR Transfer event for disabled endpoint or incorrect stream ring
21:37:33 kernel: xhci_hcd 0000:04:00.0: @00000000368b3580 9067b400 00000000 05000000 01038001

As always I've ordered a pci-e addon card with a Fresco Logic controller for
myself to see if I can come up with a better fix then the big hammer, in
the mean time this will make uas devices work again (in usb-storage mode)
for FL1000G users.
