stmhal/spi: Use software SPI if no periph id given, even if pins given.

Browse Source 
It's simpler to just default to always using software SPI if no specific
peripheral id/name is given.  To use hardware SPI users must specify a
hardware peripheral id as the first parameter to the SPI constructor.
