usb: host: xhci: purge GET_MAX_PACKET()

usb_endpoint_maxp() is now returning maxpacket
correctly - iow only bits 10:0. We can finaly remove
XHCI's private GET_MAX_PACKET macro.

usb: xhci-mtk: fix bpkts value of LS/HS periodic eps not behind TT

when a LS or FS device doesn't connect though a HS hub,
the @bPkts field of its periodic endpoint context should
be set to 1.

xhci: mediatek: support MTK xHCI host controller

There some vendor quirks for MTK xhci 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 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.
