bsp-guide: Updates to "Linux Kernel Configuration" section. 

This section was using an out-dated version of the
linux-yocto_3.10.bbappend file.  The new version accounts for
both emgd and non-emgd configurations.  I had to insert the new
listing and update some supporting text describing it.

(From yocto-docs rev: 97329a154e3dee44cb393d4a289fdcbb9f8adf07)

You can accomplish this definition by putting the configurations in a file or a set of files
inside a directory located at the same level as your kernel's append file and having the same
name as the kernel's main recipe file.
With all these conditions met, simply reference those files in a
