There is no hardware limitation for custom boards based on STM32 to uses
SPI bus with signals coming from different PORT and alternate functions.
This patch allow alternate's function definition per pin basis, thus enable
the support of SPI bus signals routed on differents PORT.

- nucleo-f334r8:
- Added USART1 and USART3 config
- nucleo-f401re:
- Changed order of UARTs to match the other boards
- nucleo-f410rb:
- Added USART6 configuration
- Fixed incorrect DMA settings (according to reference manual of the MCU)
- nucleo-f446re:
- Changed order of UARTs to match the other boards
- nucleo-l152re:
- Changed order of UARTs to match the other boards
The result of this harmonization is, that the first UART is always USART2, the
other USARTs are added in ascending order.
