- correct the names of buffers used by message queues so that it
is possible to have multiple instances of the driver (in case
such need appears in the future)
- make `stop` and `discard_rx` normal structure members, not bit
fields, as they are modified in the interrupt handler and that
could lead to overwriting of other bit fields located in the
same memory unit
- add a log message providing the actual frame clock (WS) frequency
(i.e. PCM rate) that the driver was able to configure (due to
hardware limitations, it is not always possible to achieve the
exact requested frequency and the driver selects the closest one
available, so make it more visible to users

Remove unnecessary condition that effectively limits the usability
of the I2S format to two channels mode only.
Although the description of the `i2s_config` structure contains
a remark that for the I2S format the specified number of channels
is ignored and always two are used, in fact only one other in-tree
driver (i2s_sam_ssc) applies such limitation.
The nRF I2S hardware has no problem with handling the I2S format
with audio data for only one channel, so there is no need for having
this limitation in the driver, and without such mode of operation of
the driver it is impossible to feed it with PCM data directly from
the PDM peripheral working in one channel mode.

When creating a socket, all of the registered socket implementation are
processed in a sequence, allowing to find appropriate socket
implementation for specified family/type/protocol. So far however,
the order of processing was not clearly defined, leaving ambiguity if
multiple implmentations supported the same set of parameters.
Fix this, by registering socket priority along with implementation. This
makes the processing order of particular socket implementations
explicit, giving more flexibility to the user, for example when it's
neeed to prioritze one implementation over another if they support the
same set of parameters.

Put the maximum number of bytes into Tx FIFO in the fill_fifo routine
to reduce CPU usage.
Previously, the THRE bit was checked in a loop, but, according to doc -
"In the FIFO mode, it is set when the XMIT FIFO is empty, and is
cleared when at least one byte is written to XMIT FIFO.", so only one
byte was transferred every interrupt. That was generating a big amount
of interrupts, which consumes CPU time.

This implements support for the optional Interrupt Translation Service
(ITS) module of the GICv3 Interrupt Controller.
The current implementation is designed for MSI/MSI-X interrupt delivery
in mind.
The gicv3 driver calls each ITS INVALL command when LPI interrupts are
enabled/disabled.
A simple atomic integer is used to allocate unique LPI INTIDs to ITS
users.
CPUs numbers are directly mapped as ICIDs into the Collections Table.
As a limitation it doesn't support indirect Device table to simplify
implementation but may use a large amount of memory.
INV, DISCARD, MOVI and MOVALL commands are not implemented.

This reverts commit 43309296b8.
Fixes: #38403
The referred commit introduced `zephyr_library()` for pinmux drivers but
also resulting in #38403 because several boards has `CONFIG_PINMUX=y`
without selecting any pinmux drivers from `drivers/pinmux` thus
generating the following warning:
> No SOURCES given to Zephyr library: drivers__pinmux
>
> Excluding target from build.
This commit reverts the changes so that this warning disappears.
This results in pinmux drivers from `drivers/pinmux` to be located in
libzephyr.a which is messy, but has been so for a long time, even before
Zephyr 1.14 LTS.
The future pinctrl API will be designed in such a way that this problem
will not occur. Thus the old behavior is acceptable until the transition
to pinctrl API has completed.

GPIO initialization was moved to PRE_KERNEL_1 with commit
590162a5cc06c72b70dee93f410b878bc0935f1f.
This had the consequence of having AFIO init done after GPIO init
as a consequence, this sequence ends up with AFIO clock disabled,
and hence negative impact on AFIO expected services.
Additionally, to save some flash, compile out afio init when not
required.

to the common drivers__ethernet Zephyr library.
Instead of creating a dedicated library for just two files those files
are now added to the common ethernet library, see also #8826.
Instead, the dedicated compile definitions required for those files are
specified using COMPILE_DEFINITIONS on the source files.
This also avoids the following warning as the ethernet library is no

Adding NET_DRIVERS menuconfig so that network drivers are grouped
together in its own menu entry under drivers, similar to most other
drivers.
This further has the advantages that `CONFIG_NET_DRIVERS` can be used
for testing to determine if network drivers has been selected.
This changed revealed a dependency loop where both `select` (for SLIP)
and `depends` (for PPP) which both depends on NET_DRIVERS` where in use
in the dependency tree for Qemu networking, especially NET_SLIP_TAP.
This is handled by defaulting `NET_DRIVERS` to `y` when building for a
Qemu target.
`SLIP` had a dependency to `!QEMU_TARGET || NET_QEMU_SLIP`. This is
changed so that SLIP prompt depends on `!QEMU_TARGET` which provides
full user control in hardware but makes the symbol promptless on Qemu
targets.

The stm32wl version of the sx126x driver disables the NVIC interrupt in
the radio isr to prevent retriggering while the event gets handled in
the workqueue. Since the interrupt condition is still present while the
line is disabled, the interrupt pending bit remains set in the NVIC, so
after the handler finished, when irq_enable() gets called, the interrupt
fires immediately again with no status bit set in the radio registers.
Apart from the no-op interrupt, this has the side effect of bringing
the radio out of sleep as soon as the interrupt bit are read and
cleared, which increases the idle state power consumption.
Adding a NVIC_ClearPendingIRQ() before irq_enable() seems to fix the
problem. It should not cause any issue with missing interrupt events, as
if there are pending bit on the Radio, the NVIC pending bit would be
re-set immediately.
