usb: xhci: add quirks flag to support MediaTek xHCI 0.96
There some vendor quirks for MTK xHCI 0.96 host controller:
1. It defines some extra SW scheduling parameters for HW
to minimize the scheduling effort for synchronous and
interrupt endpoints. The parameters are put into reserved
DWs of slot context and endpoint context.
2. 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.
