[Qemu-arm] MPU/MCU vs board setting cpu-type

[James Hanley]

Would it make more sense that the MPU/MCU implementation (ie
stm32f205_soc.c) define the property for the ARM_CPU_TYPE_NAME instead
of the support board (ie netduino2.c)?

It seems like a chip die version should have that property inherently
set by its init function since it will always be the same core type
for that chip die - and for a board, if it includes that chip die in
the init, then it will incorporate that core type.
