usb: musb: core: set has_tt flag

commit ec95d35a6bd0047f05fe8a21e6c52f8bb418da55 upstream.

MUSB is a non-standard host implementation which
can handle all speeds with the same core. We need
to set has_tt flag after commit
d199c96d41d80a567493e12b8e96ea056a1350c1 (USB: prevent
buggy hubs from crashing the USB stack) in order for
MUSB HCD to continue working.
