Netduino Plus 2 Machine Model

This patch series adds the Netduio Plus 2 Machine to QEMU.

Information on the board is avaliable here:
http://netduino.com/netduinoplus2/specs.htm

The git tree is avalible at:
https://github.com/alistair23/qemu/tree/csse4080.1

Some notes about this implementation:
The Netduino Plus 2 has a Cortex-M4 in it, while this model uses a Cortex-M3 as that is supported by QEMU. This means that the code that runs on the Netduino Plus 2 is recompiled for a Cortex-M3 with out Floating Point or DSP optimisations.

For my use of this it doesn't matter if the code has to be recompiled, so I have no desire to add support for the Cortex-M4.

Code compiled for the Cortex-M3 (and QEMU) can still be run nativly on the Netduino Plus 2 (this has been tested).

Some example code that runs on QEMU and the actual board is avaliable
at: https://github.com/alistair23/CSSE3010-QEMU-Examples

All of the peripherals that have been added work, although they will probalbly need to be extended apon as more complex examples are tested. They are enough to boot and run bare metal code from the examples above.

I have plans to add more devices and ideally be able to boot FreeRTOS on QEMU.

The board is similar to the Stellaris boards, but it doesn't use the same init functions armv7m_init() as that doesn't allow the configuration that is required for this board.

There is a bit of a reset address hack due to the memory offsets, I couldn't find a better way around that
