Prevent the driver from perfroming transfer when SPI_LINES_OCTAL flag
is specified, as this driver supports only SPI_LINES_DUAL for now.

To facilitate changing this driver, decouple rtio from functions not
specific to RTIO. This also requires moving the sdk driver handle
creation outside of the configure call. An effect of this is we can
stop initializing an unused sdk driver handle for the dma path.

These changes:
* Fix the check of the word size to be more useful
- check min frame size instead of max
- check for min word size requirement
- add a clarifying comment about what the word size represents in
hardware since the nomenclature from zephyr does not match the nxp
references
* Add a clarifying comment about half duplex being supported by hardware
* Add LPSPI_ namespace to defines
* Change chip select error message to be more clear about the problem
* Move the check of the clock device being ready to the lpspi init,
instead of checking it every time on configure. It probably also makes
more sense to not ready the lpspi device if the clock is not ready.
* Move the bare-metal configuration of bit fields AFTER the SDK Init
call.
* Return the proper error code if clock control call errors.

If CONFIG_SPI_STATS is enabled, the device state for all SPI controller
drivers must contain the SPI stats. This space is allocated by calling
Z_SPI_INIT_FN as part of the device definition; this is done automatically
when using SPI_DEVICE_DT_DEFINE instead of DEVICE_DT_DEFINE. If space for
statistics is not properly allocated but CONFIG_SPI_STATS is enabled, an
unexpected write to memory outside of the stats region may occur on a SPI
transfer. This commit uses SPI_DEVICE_DT_DEFINE or
SPI_DEVICE_DT_INST_DEFINE for all in-tree SPI controller drivers.

The Smartbond SPI driver enables DMA acceleration by default. However
no DMA configuration is provided in the SPI node, resulting in run
time errors when the SPI interface is used. Instead, the application
should explicitly enable DMA acceleration and select the DMA channels
and priorities.

Remove unneeded prepare_start function since all uses of it are paired
with the start function. Also, probably should not mess with chip select
before deciding to do the transfer. And just return on some error like
the rest of the driver does instead of assert.

Small change to consolidate the amount of lines of code in
the spi_mcux_isr by making a macro for the argument and removing
a line of code that was commented out.
Also move the ISR to be the first function in the file which is
common in many other drivers, instead of randomly in the middle of the
file. And move the isr callback to be next to the isr.

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.

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.
