spi: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

"A fairly standard release for SPI with the exception of a change to
the API for specifying chip selects done in preparation for supporting
devices with more than one chip select, this required some mechanical

for a while.

There's also a new API to allow us to support TPM chips on half duplex
controllers.

Summary:

- Refactoring in preparation for supporting multiple chip selects for
a single device, needed by some flash devices, which required a
change in the SPI device API visible throughout the tree

- Support for hardware assisted interaction with SPI TPMs on half
duplex controllers, implemented on nVidia Tedra210 QuadSPI

- Optimisation for large transfers on fsl-cpm devices

- Cleanups around device property use which fix some sisues with
fwnode

- Use of both void remove() and devm_platform_.*ioremap_resource()

- Support for AMD Pensando Elba, Amlogic A1, Cadence device mode,

spi: Replace all spi->chip_select and spi->cs_gpiod references with function call

Supporting multi-cs in spi drivers would require the chip_select & cs_gpiod
members of struct spi_device to be an array. But changing the type of these
members to array would break the spi driver functionality. To make the
transition smoother introduced four new APIs to get/set the
spi->chip_select & spi->cs_gpiod and replaced all spi->chip_select and
spi->cs_gpiod references with get or set API calls.
While adding multi-cs support in further patches the chip_select & cs_gpiod
members of the spi_device structure would be converted to arrays & the
"idx" parameter of the APIs would be used as array index i.e.,
spi->chip_select[idx] & spi->cs_gpiod[idx] respectively.

spi: Convert to platform remove callback returning

Merge series from Uwe Kleine-König <u.kleine-koenig@pengutronix.de>:

This patch series adapts the platform drivers below drivers/spi
to use the .remove_new() callback. Compared to the traditional .remove()
callback .remove_new() returns no value. This is a good thing because
the driver core doesn't (and cannot) cope for errors during remove. The
only effect of a non-zero return value in .remove() is that the driver
core emits a warning. The device is removed anyhow and an early return
from .remove() usually yields a resource leak.

By changing the remove callback to return void driver authors cannot
reasonably assume any more that there is some kind of cleanup later.

All drivers touched here returned zero unconditionally in their remove
callback, so they could all be converted trivially to .remove_new().
