Don't trace ring pointers every time driver increases enqueue pointer after queuing a TRB, or dequeue pointer after handling an event. These xhci_inc_deq: and xhci_inc_enq: trace entries fill up the trace and provides little useful info now that the TRB DMA address is printed with the TRB itself. Only trace ring during xhci_inc_enq() and xhci_inc_deq() in case we move to a new ring segment. Also don't show both segment and TRB addess in trace. Segment is just TRB with 0xfff masked off.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
