Yannick Gicquel d37adee32d boards/stm32-based: allow SPI signals routed on multiple alternate functions
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.
