Add MEC172x full duplex qmspi driver version to support full
duplex transfers as expected by the Zephyr spi driver model.
On every spi clock we transmit one bit and receive one bit.
This driver will work with Zephyr SPI NOR driver.

If the thread that submits data over spi is interrupted by a higher
priority thread while pushing data to the tx fifo the hardware pushes
data to spi and frees up space in the fifo. In this case more than
8 Bytes are written to the tx fifo and bytes in the rx fifo get lost
before they are collected in the rx while loop.
To avoid this, the tx loop is exited after a maximum of 8 bytes and the
rx loop will run until it collected all bytes from the rx fifo.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

west.yml: update hal_espressif to use latest v4.4.1 updates.
This change needs to be insync with esp32c3 timer changes, otherwise it
breaks it.
drivers: timer: update esp32c3 systimer to meet API changes.
Systimer API was refactored in hal v4.4.1, which
requires updates in esp32C3 systimer. Timer behavior is maintained
as is.

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.

Adds optional device tree property to specify a default character
to clock out when the TX buffer pointer is NULL. If the property is
not set the existing behavior (default char of 0x00) is used.
I verified the expected behavior using an i.MX RT685 board and

DT nodes aren't guaranteed to define a label property. But emulated bus
controllers currently make use of this property to dispatch to the
associated emulator.
Have emulated bus controllers use DEVICE_DT_GET(node_id) to dispatch to
right target peripheral emulator. This also change makes emul_get_binding
and device_get_binding synonymous in behavior with respect to their
parameters.
This also strictly enforces a 1:1 correspondence between invocations of
DEVICE_DT_DEFINE and EMUL_DEFINE.

Allow emulator creators to write an init function that can be used
across multiple busses so as to reduce the boilerplate and cognitive
load in creating an emulator.
Part of this change includes allowing access to the emul struct from a
field in a {bus}_struct api (e.g. i2c_struct), which removes the need for
sporadic usages of CONTAINER_OF to access the emul struct.
Overall, this change simplifies and reduces the amount of boilerplate
code to get a device emulator up and running, thus reducing excise work
to writing tests.
