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

Browse Source 
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)
