Damien George 58ebeca6a9 drivers/bus: Pull out software SPI implementation to dedicated driver. 
This patch takes the software SPI implementation from extmod/machine_spi.c
and moves it to a dedicated file in drivers/bus/softspi.c.  This allows the
SPI driver to be used independently of the uPy runtime, making it a more
general component.
