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.

Remove address-of operator ('&') when assigning `init_fn`
function pointer in `DEVICE_DT_INST_DEFINE` macro.
This change aims to maintain consistency among the drivers in
`drivers/spi`, ensuring that all function pointer assignments
follow the same pattern.

Set Spi StateIndex equal to index of DT Spi node.
Because number of State array is set base on
number of DT Spi node used. If StateIndex is set
equal to Spi instance, StateIndex can be over array.

At present, many of the NXP S32 shim drivers do not make use of
devicetree instance-based macros because the NXP S32 HAL relies on an
index-based approach, requiring knowledge of the peripheral instance
index during both compilation and runtime, and this index might not
align with the devicetree instance index.
The proposed solution in this patch eliminates this limitation by
determining the peripheral instance index during compilation
through macrobatics and defining the driver's ISR within the shim
driver itself.

Use clock control API to retrieve the module's frequency and
update the boards using it to provide the source clocks.

Following #56576, the `cs` field in `struct spi_config` is of type
`struct spi_cs_control` instead of a pointer to the same type.
This PR updated the driver to use `spi_cs_is_gpio()` helper to
check if SPI CS is controlled using a GPIO.
