get GPIO and USART ports working.

Browse source 
The STM32F3DISCOVERY board would crash when setting GPIOA Pin_13 or
Pin_14 to analog mode so they are excluded in the gpio initialisation.

The USART GPIO configuration did not work when using the F10x code.  The
USART status and DMA registers are different too.
