tools/memory-model: Move Documentation description to Documentation/README

This commit moves the descriptions of the files residing in
tools/memory-model/Documentation to a README file in that directory,
leaving behind the description of tools/memory-model/Documentation/README
itself.  After this change, tools/memory-model/Documentation/README
provides a guide to the files in the tools/memory-model/Documentation
directory, guiding people with different skills and needs to the most
appropriate starting point.

+It has been said that successful communication requires first identifying
+what your audience knows and then building a bridge from their current
+knowledge to what they need to know.  Unfortunately, the expected
+Linux-kernel memory model (LKMM) audience might be anywhere from novice
+to expert both in kernel hacking and in understanding LKMM.
+
+This document therefore points out a number of places to start reading,
+depending on what you know and what you would like to learn.  Please note
+that the documents later in this list assume that the reader understands
+the material provided by documents earlier in this list.

+o	You are new to Linux-kernel concurrency: simple.txt

+o	You are familiar with the Linux-kernel concurrency primitives
+	that you need, and just want to get started with LKMM litmus
+	tests:  litmus-tests.txt
+
+o	You are familiar with Linux-kernel concurrency, and would
+	like a detailed intuitive understanding of LKMM, including
+	situations involving more than two threads:  recipes.txt
+
+o	You are familiar with Linux-kernel concurrency and the use of
+	LKMM, and would like a quick reference:  cheatsheet.txt
+
+o	You are familiar with Linux-kernel concurrency and the use
+	of LKMM, and would like to learn about LKMM's requirements,
+	rationale, and implementation:	explanation.txt
+
+o	You are interested in the publications related to LKMM, including
+	hardware manuals, academic literature, standards-committee
+	working papers, and LWN articles:  references.txt
