Note that our "App" is more than a userspace "app"

It's also a FIQ interrupt handler and some 'drivers' (for the GSM
specific stuff like DSP / TPU and the RF / external chips).
I'm also leaning toward having the board definition separate (at least
part of them) since they'll including things like RFFE stuff that will
only be useful for the GSM stuff.
