Employ a code spell checking tool to scan and correct spelling errors
in all files within the drivers/spi directory.

Implements the SPI RTIO API. Refactors many of the internal transfer
functions to work on simple types to allow for both the RTIO and existing
SPI API functions to co-exist.
Removes the unneeded shift_master specialization. Either a polling or DMA
transfer flow is used when used with RTIO as all operations are normalized.
When SPI_RTIO is enabled the spi_transceive blocking call translates
the request into an RTIO transaction placed in the queue of transactions
the device is meant to do.

For larger transfers DMA can be used enabling other tasks
to continue running. A threshold of 32 byte transfers
is about right and is defined threshold value for using DMA.
This does not currently support multiple SPI transactions changing
chip select with DMA (though the hardware supports this) currently.
Instead opting for the simpler first change of enabling one shot
DMA SPI transfers for those where the size warrants it.
Adds the loopback binding option to enable the spi_loopback test.

Update spi drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.

The SAM spi driver depends on GPIO driver to work. It seems that this
dependency chain it is not handled. This select GPIO driver when SPI
driver is enabled. It rework GPIO and SPI Kconfig to select driver by
devicetree and drop entries at Kconfig.defconfig.series file.

Reworked spi_sam driver to utilize new DT_INST macros as part of
this rework we also now get pin ctrl/mux configuration information
from the device tree instead of via Kconfig and defines in soc_pinmap.h
We remove defines from dts_fixup.h and soc_pinmap.h and associated
Kconfig symbols that are no longer needed due to getting all that
information from devicetree.

The current sam spi driver uses soc dependent name which duplicate
configuration to enable other platforms. This refactor current
definitions to a generic way to reuse symbols by multi soc definitions.

Use this short header style in all Kconfig files:
# <description>
# <copyright>
# <license>
...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just
# Foo-related options
It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

Make sure that when e.g. CONFIG_SERIAL is set, CONFIG_UART_SAM0 is
selected automatically when the sam0 SoC family is used.

All drivers require DTS for their primary SPI settings.
Removing SPI_[0-9]_NAME config option added some more samples changes.
Usage of these options there was anyway not relevant.

Move to using Kconfig (like other Atmel SAM drivers do) to specify the
pinmux setting for SAMe70 SoCs. Updated the sam_e70_xplained board to
set the default in Kconfig.defconfig instead of via board.h
