Since this manual is about BSP and not Poky as is the Poky Reference
Manual I updated the title page to include the title combined with the
Yocto Project logo. So for the background-image url in the .authorgroup
style I replaced the poky-ref-manual.png file with bsp-title.png.
Updates affect both the PDF and HTLM versions of the BSP Guide.
