Log:
MFC 1.42, 1.43: Let the EHCI hardware track the toggle state for
bulk and interrupt transfers. This fixes some cases where the
software toggle tracking was not doing the right thing. For example,
a short transfer that transferred 0 bytes of the requested qTD
transfer size does cause a toggle change, but the existing code was
assuming it didn't.
