DeviceTree

We want to use DeviceTree to allow MicroPython to automatically customize itself based on the FPGA configuration.

This involves 3 parts;

• Making LiteX / Migen+MiSoC generate DeviceTree - https://github.com/upy-fpga/issues-wiki/issues/6
• Making MicroPython understand DeviceTree - https://github.com/upy-fpga/issues-wiki/issues/7
• Adding support for peripherals under MicroPython

This has other useful advantages;

• LiteX / Migen+MiSoC supporting DeviceTree makes porting Linux to it possible.
• MicroPython understanding DeviceTree makes it easier to port MicroPython to more SoCs.
