py/misc.h: Remove unused count_lead_ones() inline function.
This function was never used for unicode/utf8 handling code, or anything
else, so remove it to keep things clean.

esp8266/esp_mphal.h: Fix I2C glitching by using input mode for od_high.
Certain pins (eg 4 and 5) seem to behave differently at the hardware level
when in open-drain mode: they glitch when set "high" and drive the pin
active high for a brief period before disabling the output driver. To work
around this make the pin an input to let it float high.

stm32/qspi: Do an explicit read instead of using memory-mapped mode.
Using an explicit read eliminates the need to invalidate the D-cache after
enabling the memory mapping mode, which takes additional time.

stm32/storage: Introduce MICROPY_HW_ENABLE_INTERNAL_FLASH_STORAGE cfg.
This config variable controls whether to support storage on the internal
flash of the MCU. It is enabled by default and should be explicitly
disabled by boards that don't want internal flash storage.

stm32/storage: Remove all SPI-flash bdev cfg, to be provided per board.
If a board wants to use SPI flash for storage then it must now provide the
configuration itself, using the MICROPY_HW_BDEV_xxx macros.

stm32/storage: Merge all misc block-dev funcs into a single ioctl func.
It makes it cleaner, and simpler to support multiple different block
devices. It also allows to easily extend a given block device with new
ioctl operations.

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.
