[PATCH 3/4] xhci: add TSP bitflag to TRB tracing

[Mathias Nyman <mathias.nyman@linux.intel.com>]

Software can set a Transfer State Preserve (TSP) flag to maintain
data toggle and sequence number when issuing a reset endpoint
command.

xhci driver is using TSP for soft retry, we want to show TSP usage
in tracing as well
