USB: xhci: Add tests for TRB address translation.

Browse source

It's not surprising that the transfer request buffer (TRB) physical to
virtual address translation function has bugs in it, since I wrote most of
it at 4am last October.  Add a test suite to check the TRB math.  This
runs at memory initialization time, and causes the driver to fail to load
if the TRB math fails.

Please excuse the excessively long lines in the test vectors; they can't
really be made shorter and still be readable.
