docs: power: convert docs to ReST and rename to *.rst
Convert the PM documents to ReST, in order to allow them to
build with Sphinx.
The conversion is actually:
- add blank lines and indentation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

+====================================================
+Testing suspend and resume support in device drivers
+====================================================
+
+ (C) 2007 Rafael J. Wysocki <rjw@sisk.pl>, GPL
+
+1. Preparing the test system
+============================
+
+Unfortunately, to effectively test the support for the system-wide suspend and
+resume transitions in a driver, it is necessary to suspend and resume a fully
+functional system with this driver loaded. Moreover, that should be done
+several times, preferably several times in a row, and separately for hibernation
+(aka suspend to disk or STD) and suspend to RAM (STR), because each of these
+cases involves slightly different operations and different interactions with
+the machine's BIOS.
+
+Of course, for this purpose the test system has to be known to suspend and
+resume without the driver being tested. Thus, if possible, you should first
+resolve all suspend/resume-related problems in the test system before you start
+testing the new driver. Please see Documentation/power/basic-pm-debugging.rst
+for more information about the debugging of suspend/resume functionality.
+
+2. Testing the driver
+=====================
+
+Once you have resolved the suspend/resume-related problems with your test system
+without the new driver, you are ready to test it:
+
+a) Build the driver as a module, load it and try the test modes of hibernation
+ (see: Documentation/power/basic-pm-debugging.rst, 1).
+
+b) Load the driver and attempt to hibernate in the "reboot", "shutdown" and
+ "platform" modes (see: Documentation/power/basic-pm-debugging.rst, 1).
+
+c) Compile the driver directly into the kernel and try the test modes of
+ hibernation.
+
+d) Attempt to hibernate with the driver compiled directly into the kernel
+ in the "reboot", "shutdown" and "platform" modes.
+
+e) Try the test modes of suspend (see: Documentation/power/basic-pm-debugging.rst,
+ 2). [As far as the STR tests are concerned, it should not matter whether or
+ not the driver is built as a module.]
+
+f) Attempt to suspend to RAM using the s2ram tool with the driver loaded
+ (see: Documentation/power/basic-pm-debugging.rst, 2).
+
+Each of the above tests should be repeated several times and the STD tests
+should be mixed with the STR tests. If any of them fails, the driver cannot be
+regarded as suspend/resume-safe.
