The xHCI 1.0 specification changes the format of the TD size field in
Normal and Isochronous TRBs. The field in control TRBs is still set to
reserved zero. Instead of representing the number of bytes left to
transfer in the TD (including the current TRB's buffer), it now represents
the number of packets left to transfer (*not* including this TRB).
See section 4.11.2.4 of the xHCI 1.0 specification for details. The math
is basically copied straight from there.
Create a new function, xhci_v1_0_td_remainder(), that should be called for
all xHCI 1.0 host controllers. The field location and maximum value is
still the same, so reuse the old function, xhci_td_remainder(), to handle
the bit shifting.
