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.

No need to specify SX127X_PARAMS structure as it is already
defined in drivers/sx127x/include/sx127x_params.h.
Also remove SX127X_PARAM_SPI and SX127X_PARAM_PASELECT as their
values are the same as default ones.
