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.

Removed PM device runtime support from drivers in PD_SYS domain.
Update the rest device drivers to call pm_device_runtime_get/put()
functions when CONFIG_PM_DEVICE_RUNTIME is enabled.

This commit should deal with adding support
for asynchronous operations. It also adds
support for DMA acceleration via a Kconfig
variable (enaled by default as DMA should
be considered scales faster than the
interrupt-driven approach).

Code adds pm action function that stores SPI configuration
before PD_COM is allowed to be turned off.
PM_DEVICE_RUNTIME scheme is also supported

This adds the SPI driver for the Renesas SmartBond(tm) DA1469x MCU family.
The driver only supports controller mode. All four SPI modes are supported.
Note that the lowest supported speed is 2285714Hz.
Requesting speeds higher than 16MHz, will result in a 16MHz SCLK.
