stm32f107_basic: Add support for a simple stm32f107 platform

Browse source 
This platform is a basic waveshare stm32f107 devkit which contains a
USART, USB device port, some buttons and some LEDs.  Unfortunately not
enough to bring up networking, but enough to test building and a
simple contiki shell
