kernel-dev: Added KMACHINE and MACHINE descriptions for using metadata
Needed to remove an old example that was showing how two BSPs could share the same KMACHINE value. I replaced it with corei7-based machines. Also noted that KMACHINE is for kernel mapping only whereas MACHINE is for the layer's BSP machine type.
