There some vendor quirks for MTK xhci host controller:
1. It defines some extra SW scheduling parameters for HW

   interrupt endpoints. The parameters are put into reseved
   DWs of slot context and endpoint context.
2. Its IMODI unit for Interrupter Moderation register is
   8 times as much as that defined in xHCI spec.
3. Its TDS in  Normal TRB defines a number of packets that
   remains to be transferred for a TD after processing all
   Max packets in all previous TRBs.

I just rewrote and unified the the xhci TD remainder functions,
now we got only one xhci_td_remainder() function which should
be more suitable for quirks.

You can add the quirk directly to it, no need to duplicate the
whole function.
