Tom Burdick 4c20403629 spi: callback API for asynchronous transcieve 
Adds a new spi_transcieve_cb API which enables asynchronous
SPI transactions with callback notification.

The exist spi_transcieve_async API remains and uses the new
spi_transcieve_cb API to provide a k_poll_signal notifier.

The driver API changes to provide a callback and userdata
parameter to async transcieve. All drivers in the tree
have been updated to the change.

Gerard Marull-Paretas fb60aab245 drivers: migrate includes to <zephyr/...> 
In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Tomasz Bursztyka 01b9813d73 drivers/spi: Return an error on SPI_HALF_DUPLEX for relevant drivers 
This feature will need to be, however, implemented driver by driver

Bartosz Bilas 7ba48aa7a9 drivers: spi_xlnx_axi_quadspi: initialize all cs gpios during init 
In case when we have multiple devices connected to the
one SPI interface the initial state of CS gpios after
MCU reset is floating and it might be low that prevents us from
communicating between particular devices. Fix that by
initializing all provided cs gpios and setting them as inactive.

Bartosz Bilas ea25b92cd9 drivers: spi: use dedicated init priority 
A couple of SPI drivers use CONFIG_KERNEL_INIT_PRIORITY_DEVICE
as init priority for driver initialization. Let's change
it to the dedicated CONFIG_SPI_INIT_PRIORITY to make it
compatible with other ones.

Stefan Bigler 596cad8231 spi: fix locking for SPI_LOCK_ON using synchronous API 
Keep locking for SPI_LOCK_ON from the first call of transceive until
spi_release release the lock. Use owner parameter to in the spi_context
to store the owner of the lock.
The locking is in line with the SPI_HOLD_ON_CS

Tomasz Bursztyka ef560e0a53 drivers: Manual const-ification of device driver instance 
These are all the case that coccinelle cannot find as they are inside
macro declarations.

Fixed via:

git grep -rlz -E "\(struct device \*" |
	xargs -0 sed -i 's/(struct device/(const struct device/g'

Fixes #27399

Tomasz Bursztyka 4dcfb5531c isr: Normalize usage of device instance through ISR 
The goal of this patch is to replace the 'void *' parameter by 'struct
device *' if they use such variable or just 'const void *' on all
relevant ISRs

This will avoid not-so-nice const qualifier tweaks when device instances
will be constant.

Note that only the ISR passed to IRQ_CONNECT are of interest here.

In order to do so, the script fix_isr.py below is necessary:
