Noted.
FWIW I didn't change any code file contents except to note that a .h
file moved from libcpu/ to bsp/.
The big problem here is that when we did the BSP, we thought the
Mongoose-V on-CPU IP modules might show up again. They haven't
and moving them makes it clear they were specific to this single case.
