USB: dummy-hcd needs the has_tt flag

commit c5c69f3f0dcf9b569c8f3ad67f3af92cfcedac43 upstream.

Like with other host controllers capable of operating at both high
speed and full speed, we need to indicate that the emulated controller
presented by dummy-hcd has this ability.  Otherwise usbcore will not
accept full-speed gadgets under dummy-hcd.  This patch (as1469) sets
the appropriate has_tt flag.
