[yocto] changing kernel config in Morty build

[Zoran Stojsavljevic]

Hello Greg,

Not sure if this can help, since I do Sumo. This works for Sumo, no
idea if ths works for Morty.
https://www.yoctoproject.org/docs/2.5/kernel-dev/kernel-dev.html#using-an-in-tree-defconfig-file

Hope this helps,
Zoran
