xhci: show DMA address of TRB when tracing TRBs
The DMA address of a queued TRB is essential when looking at traces as both transfer events and command completion events refer to the command or transfer based on its DMA address. Previously the TRB address was figured out from xhci_inc_enq and xhci_inc_deq trace entries seen after queuing or handlong a TRB. Now that DMA address is shown in TRB tracing we can get rid of most of the xhci_inc_enq and xhci_inc_deq traces thus decreasing trace size.
