[meta-ti] Introducing meta-beagleboard

Thank you, Jason!

Before everyone freaks out - this is a good thing. This will enable meta-ti
and meta-beagleboard to achieve their respective goals, as it relates to the
common BeagleBone and BeagleBoard-xM platforms, w/o slowing or impeding each
other. Thank you for your understanding.

This sounds like an excellent idea. My question is when will this happen, and will migration be automatic with 'oebb.sh update'?



It seems that Koen is loaded with other tasks for the time being and
isn't currently blocked on meta-ti, but this clears the way for him
when he is ready.

You can expect it to come with './oebb.sh update'.
