drivers/memory/spiflash: Change to use low-level SPI object not uPy one.

Browse Source 
This patch alters the SPI-flash memory driver so that it uses the new
low-level C SPI protocol (from drivers/bus/spi.h) instead of the uPy SPI
protocol (from extmod/machine_spi.h).  This allows the SPI-flash driver to
be used independently from the uPy runtime.
