    yocto: slides: merge introductory slides about BSP layers
    
    These two slides cover the same topic and part of the content is
    duplicated, so merge them into one.

   \begin{itemize}
-    \item BSP layers are device specific layers. They hold metadata
-      with the purpose of supporting specific hardware devices.
-    \item BSP layers describe the hardware features and often provide
-      a custom kernel and bootloader with the required modules and
-      drivers.
-    \item BSP layers can also provide additional software, designed
-      to take advantage of the hardware features.
-    \item As a layer, it is integrated into the build system as we
-      previously saw.
-    \item A good practice is to name it \code{meta-<bsp_name>}.
