Documentation/ABI: clean up sysfs-class-pktcdvd

Clean up the sysfs documentation such that it is in the same format as
described in Documentation/ABI/README. Mainly, the patch moves the
attribute names to the 'What:' field. This might be useful for scripting
and tracking changes in the ABI.

----------------
+		add:		(WO) Write a block device id (major:minor) to
+				create a new pktcdvd device and map it to the
+				block device.
 
-The pktcdvd module (packet writing driver) creates
-these files in the sysfs:
-(<devid> is in format  major:minor )
+		remove:		(WO) Write the pktcdvd device id (major:minor)
+				to remove the pktcdvd device.

-                           it to the block device.
+		device_map:	(RO) Shows the device mapping in format:

-    remove         (0200)  Write the pktcdvd device id (major:minor)
-                           to it to remove the pktcdvd device.
 
-    device_map     (0444)  Shows the device mapping in format:
