We have had the hcd->uses_new_polling flag for many years now, so by
this time all the HCDs should be setting it. But a few laggards
aren't. Accordingly, this patch adds the flag to the drivers that
don't already set it.
I doubt this will make any difference in the drivers' behavior, but
it would be good to test the patch just in case. Please let me know if
it causes any problems.
