Use minimized PIO code for 3-wire operation.
Input and output buffers are conventionally stored in bus byte order.
For 16 and 32 bit transfers, this is effectively big-endian, so
txbuf and rxbuf need to be read as such. Those pointers also need
to be declared uint8_t * instead of void *.
In addition, tx_count and rx_count are based on dts, and refer to
whole transfers (8, 16, or 32 bits), not bytes.
Added rpi_pico.overlay to samples/sensor/magn_polling to demonstrate
32-bit word size, and updated the README.rst to make it independent
of the specific sensor.
Clean up compliance check failures.
Fix typos.
Synchronize 3-wire TX and RX cycles.

Apparently, the previous change to fix the chip select only works on
some newer revisions of the LPSPI, and the behavior is different on
older parts like RT. For now put some #ifdef to keep the fixed CS on
MCXN but have the old behavior on RT and other platforms.

Make clear in the include/ header that data frame size
is the same thing as word size for the context of this API.
Also, add some comments to the spi_context to make it easier
for driver writers to understand how to use the functions,
by noting the meaning of the dfs and len parameters to the update
functions. Otherwise it takes some time to understand what they mean.

The SPI stm32 H7 driver always suspends the SPI transaction
when finishing the transceive operation. This, according to
the stm32 H7 datasheet, must only be done when the SPI master
is configured as receive-only, and the driver always
configures it as full-duplex.
Hence, remove this unnecessary operation for clarify and for
a potential reduction in the minimum time between SPI
transceive operations.

Fix the chip select when using the synchronous API with DMA path.
Note need to use TxDataRequest flag instead of ModuleBusy flag now
because module busy flag will not deassert until PCS deasserts.
This does not fix CS for the non-DMA path, because that would require a
large driver rework.
Do not skip configuration when calling transceive with the same spi_cfg
because we need to write a new command word.

Extracted common SPI RTIO operations from the spi_mcux_lpspi driver
into spi_rtio, which should be common across RTIO drivers.
Tested with spi_loopback with and without CONFIG_SPI_RTIO. Ran on

Also, verified the other SPI RTIO driver (spi_sam) is not broken by
these changes (tested building for target: robokit1 with the same
