documentation/bsp-guide/bsp.xml: Removal of certain layers 

Wording changed to remove example BSP layers that really weren't
layers (e.g. meta-intel).  One of three patches from Tom.

The Yocto Project organizes BSP Layers within the Yocto Metadata Layers area
of the Yocto Project Source Repositories at
<ulink url='&YOCTO_GIT_URL;/cgit.cgi'></ulink>.
If you examine the source repositories, you will find many BSP Layers.
Here are a few:
<literallayout class='monospaced'>
meta-baryon
meta-fsl-ppc
meta-intel
meta-selinux
meta-ti
</literallayout>
It is worth noting that the <filename>meta-intel</filename> BSP Layer contains
within itself several other BSP Layers, which makes it sort of a "super" BSP layer.
Following is a sampling of the BSP Layers that the <filename>meta-intel</filename>
BSP Layer contains:
<literallayout class='monospaced'>
meta-cedartrail
meta-crownbay
meta-emenlow
meta-fishriver
meta-fri2

The layer's base directory (<filename>meta-&lt;bsp_name&gt;</filename>) is the root
of the BSP Layer.
This root is what you add to the <filename>BBLAYERS</filename>
This root is what you add to the

Some BSPs require additional layers on
top of the BSP's root layer in order to be functional.
For these cases, you also need to add those layers to the
<filename>BBLAYERS</filename> variable in order to build the BSP.
You must also specify in the "Dependiencies" section of the BSP's
<filename>README</filename> file any requirements for additional
layers and, preferably, any
build instructions that might be contained elsewhere
in the <filename>README</filename> file.
