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.

This adds support for the GRLIB SPIMCTRL SPI controller used in LEON and
NOEL-V systems. SPIMCTRL can operate in two different modes: In the
default mode it allows memory-mapped read access to the flash data. When
set in the user mode, it can be used to generate SPI bus transactions.
