documentation/dev-manual/dev-manual-kernel-appendix.xml: Add note about conflict

Browse Source 
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.

<note>
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.
