Fixes [YOCTO #837]

The n450 linux-yocto-stable bbappend was using WRMACHINE instead of KMACHINE. This resulted in KMACHINE being set to UNDEFINED by the linux-yocto.inc which resulted in bulding the common_pc-standard branch instead of the atom-pc-standard branch. This build a kernel without vfat, blk loop, and the requisite codepages.

From: Darren Hart <[email protected]>

AUTOREV should only be used for local development and that can be set using the meta-extras/meta-kernel-dev layer. Comment the subtle aspect of defaulting to the atom-pc SRCREVs due to the shared KMACHINE.
