stm32/qspi: Don't take the address of pin configuration identifiers.
...
Taking the address assumes that the pin is an object (eg a struct), but it
could be a literal (eg an int). Not taking the address makes this driver
more general for other uses.

stm32: Consolidate include of genhdr/pins.h to single location in pin.h.
...
genhdr/pins.h is an internal header file that defines all of the pin
objects and it's cleaner to have pin.h include it (where the struct's for
these objects are defined) rather than an explicit include by every user.

stm32/Makefile: Re-enable strict aliasing optimisation for ST HAL files.
...
The HAL requires strict aliasing optimisation to be turned on to function
correctly (at least for the SD card driver on F4 MCUs). This optimisation
was recently disabled with the addition of H7 support due to the H7 HAL
having errors with the strict aliasing optimisation enabled. But this is
now fixed in the latest stm32lib and so the optimisation can now be
re-enabled.
Thanks to @chuckbook for finding that there was a problem with the SD card
on F4 MCUs with the strict aliasing optimisation disabled.

stm32/can: Add "list" param to CAN.recv() to receive data inplace.

operations, such as pyb.SPI.recv(buf).

stm32: Use STM32xx macros instead of MCU_SERIES_xx to select MCU type.
...
The CMSIS files for the STM32 range provide macros to distinguish between
the different MCU series: STM32F4, STM32F7, STM32H7, STM32L4, etc. Prefer
to use these instead of custom ones.

stm32/can: Use explicit byte extraction instead of casting to word ptr.

older gcc compilers.

stm32/can: Improve can.recv() so it checks for events, eg ctrl-C.
...
This patch provides a custom (and simple) function to receive data on the
CAN bus, instead of the HAL function. This custom version calls
mp_handle_pending() while waiting for messages, which, among other things,
allows to interrupt the recv() method via KeyboardInterrupt.

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

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.
