documentation/dev-manual/dev-manual-kernel-appendix.xml: Add note about conflictdenzil-7.0.1_rc2denzil-7.0.1

Added a note to the part of the example where you bitbake the kernel
after turning off CONFIG_SMP.  The warnings you get can cause confusion.
the note explains they are normal.

+                Manually turning off a kernel configuration setting such as 
+                <filename>CONFIG_SMP</filename> can cause the kernel configuration audit
+                to issue warnings during the build. 
+                In this example, warnings appear telling you that the expected value
+                <filename>CONFIG_SMP</filename> does not appear in the <filename>.config</filename>
+                file.
+                Because in this example you specifically turned off <filename>CONFIG_SMP</filename>,
+                you can safely ignore the apparent conflict.
