BSP Guide and BSP Chapter: Sync'ed these two files

After moving BSP Guide into its own folder for documentation I discovered
a consequence of that.  There are two separate bsp.xml files now:  one
in the poky-ref-manual folder and one in the bsp folder.  I had done some
good cleanup work in the version in the poky-ref-manual folder.  This
commit reflects a 'meld' operation where I re-sync'ed the bsp.xml
file in the bsp-guide folder to be the same (almost) as the one in the
poky-ref-manual folder.  There is still one slight difference between the
two files due to one's context as a stand-alone manual and the other as
a section in a larger book.
