[PATCH v3 1/3] doc: fine-tune the documentation of the 'm' RSP packet

[Tankut Baris Aktemur <tankut.baris.aktemur@intel.com>]

Revise a sentence to avoid misinterpretation.  Move @cindex entries
before the text they index.  Refer to trace frames regarding partial
reads.

 The stub need not use any particular size or alignment when gathering
 data from memory for the response; even if @var{addr} is word-aligned
 and @var{length} is a multiple of the word size, the stub is free to
 use byte accesses, or not.  For this reason, this packet may not be
 suitable for accessing memory-mapped I/O devices.
