Andrew Leech 30501d3f54 drivers, stm32: Support SPI/QSPI flash chips over 16MB. 
With a SPI flash that has more than 16MB, 32-bit addressing is required
rather than the standard 24-bit.  This commit adds support for 32-bit
addressing so that the SPI flash commands (read/write/erase) are selected
automatically depending on the size of the address being used at each
operation.

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.

Damien George 1da2d45de6 drivers/bus: Add QSPI abstract type with software QSPI implementation. 
A new directory drivers/bus/ is introduced, which can hold implementations
of bus drivers.  A software QSPI implementation is added.
