Since we don't have a MMU, it's not much of a difference and there is no
real userspace. We can still register IRQs etc. I would suggest that the
GSM specific calls in board_init are moved to the "userspace" user_start
function. For the MT6235, we need a cleaner API once it runs Linux. But
for now on Nuttx, the current things are fine.

I'll add FIQs and extend the interface to support them soon.

Well, the configs directory holds board specific stuff. However, it's
probably not the appropriate place since it doesn't belong to the OS bit
is GSM related.
