Fixes documentation build warnings related to indentation and text
formatting, such as:

Documentation/misc-devices/dw-xdata-pcie.rst:20: WARNING: Unexpected
indentation.
Documentation/misc-devices/dw-xdata-pcie.rst:24: WARNING: Unexpected
indentation.
Documentation/misc-devices/dw-xdata-pcie.rst:25: WARNING: Block quote
ends without a blank line; unexpected unindent.
Documentation/misc-devices/dw-xdata-pcie.rst:30: WARNING: Unexpected
indentation.
Documentation/misc-devices/dw-xdata-pcie.rst:34: WARNING: Unexpected

Documentation/misc-devices/dw-xdata-pcie.rst:35: WARNING: Block quote
ends without a blank line; unexpected unindent.
Documentation/misc-devices/dw-xdata-pcie.rst:40: WARNING: Unexpected
indentation.

Also fixes some outdated information related to stop file interface in sysfs.

In the future, there's no need to wrap error/warning lines like this in
a changelog text.  Not a big deal, but the above is messy to read,
right?

When you say "also", that means you need a separate patch usually.  And
for this patch, that is exactly what you need.  Please split this up
into one patch that fixes the reported problem, and another one that
adds the needed information.

+Description
+-----------
+
 This driver should be used as a host-side (Root Complex) driver and Synopsys
 DesignWare prototype that includes this IP.
 
-The "dw-xdata-pcie" driver can be used to enable/disable PCIe traffic
+The dw-xdata-pcie driver can be used to enable/disable PCIe traffic
 generator in either direction (mutual exclusion) besides allowing the
 PCIe link performance analysis.
 
 The interaction with this driver is done through the module parameter and
 can be changed in runtime. The driver outputs the requested command state

+Example
+-------
+
+Write TLPs traffic generation - Root Complex to Endpoint direction
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Generate traffic::
+
+        # echo 1 > /sys/class/misc/dw-xdata-pcie.0/write
 
-Request write TLPs traffic generation - Root Complex to Endpoint direction
-- Command:
-	echo 1 > /sys/class/misc/dw-xdata-pcie/write
+Get link throughput in MB/s::
 
-Get write TLPs traffic link throughput in MB/s
-- Command:
-        cat /sys/class/misc/dw-xdata-pcie/write
-- Output example:
+        # cat /sys/class/misc/dw-xdata-pcie.0/write
 	204
 
-Request read TLPs traffic generation - Endpoint to Root Complex direction:
-- Command:
-	echo 1 > /sys/class/misc/dw-xdata-pcie/read
+Stop traffic in any direction::
 
-Get read TLPs traffic link throughput in MB/s
-- Command:
-        cat /sys/class/misc/dw-xdata-pcie/read
-- Output example:
+        # echo 0 > /sys/class/misc/dw-xdata-pcie.0/write

+Read TLPs traffic generation - Endpoint to Root Complex direction

-Request to stop any current TLP transfer:
-- Command:
