documentation/bsp-guide/bsp.xml: Updated Example Filesystem Layout 

Added more explanation about the base directory (meta-<bsp_name>) to the
Example Filesystem Layout section.  These changes were suggested by
Tom Zanussi to help users understand better how to add BSP layers
to the build system.

"bsp_name" is a placeholder for the machine or platform name.
Here are some example base directory names:

The base directory (<filename>meta-&lt;bsp_name&gt;</filename>) is the root of the BSP layer.
This root is what you add to the BBLAYERS variable in <filename>build/conf/bblayers.conf</filename>
so that the build system recognizes the BSP definition and from it can build an image.
Here is an example:
<literallayout class='monospaced'>
BBLAYERS = " \
/usr/local/src/yocto/meta \
/usr/local/src/yocto/meta-yocto \
/usr/local/src/yocto/meta-&lt;bsp_name&gt; \
"
</literallayout>

While you can use this basic form for the standard, realize that the actual structures
