Andrew Leech 7ee5afe8d1 drivers/bus: Detect QSPI transfer errors and pass up to spiflash driver.
This changes the signatures of QSPI write_cmd_data, write_cmd_addr_data and
read_cmd_qaddr_qdata so they return an error code.  The softqspi and stm32
hardware qspi driver are updated to follow this new signature.  Also the
spiflash driver is updated to use these new return values.

Damien George 54f1694ab6 drivers/bus: Rename MP_SPI_ADDR_IS_32B to MICROPY_HW_SPI_ADDR_IS_32BIT.
And allow it to be configured externally, if needed.

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.
