When the driver was called to set the period length for a channel
to 0, it set the COUNTERTOP register in the PWM peripheral to 0,
what resulted in an undefined behavior of the peripheral (and lack
of the STOPPED event sometimes).
The PWM API does not precise how should a zero length period be
handled; some drivers return the -EINVAL error in such case, some
do not. This patch fixes the pwm_nrfx driver so that it does not
change the previously used COUNTERTOP register value when the period
length is set to 0, and because the pulse cycles are always limited
by the driver to period cycles (so 0 in this case), in result the
relevant channel is simply deactivated. This allows users to switch
off a channel by requesting the pulse width to be set to 0 without
providing a non-zero period in such call.

On LSM6DSO sensor the INT1 pin is used for both generating the drdy
interrupt and for switching to I3C hotjoin mode just after reset if
it is at logical '1' level. It might happen that after a board
reset the logical level '1' is preserved (maybe a level shifter)
forcing the LSM6DSO to enter erroneously in I3C mode, breaking any
attempt to communicate with it. (Fix#38902)

In some configurations (e.g. edge interrupt triggers),
an interruptible event occurs during ISR and the host interrupt
controller does not see the new event due to IIR is constantly
asserting interrupts. For example, the callback handles RX and
then TX. If another character comes in before end of TX processing
(TX interrupt still asserts while raising RX interrupt), the host
interrupt controller may not see this new event. So if needed,
the IER is being toggled to re-assert interrupts at the end of ISR
to nudge the host interrupt controller to fire the ISR again.

GPIO L/K groups:
On IT81202 (128-pins package), the pins of GPIO group K and L aren't
bonding with pad. So we configure these pins as internal pull-down
at default to prevent leakage current due to floating.
GPIOH7:
On IT81202/IT81302, the GPIOH7 isn't bonding with pad and is left
floating internally. We need to enable internal pull-down for the pin
to prevent leakage current, but IT81202/IT81302 doesn't have the
capability to pull it down. We can only set it as output low,
so we enable output low for it at initialization to prevent leakage.

Timer STM32 LPTIM currently supports 2 clocks sources: LSE & LSI.
LSE (external) is defined as default but its availability depends
on board support package and then may not be available.
This ends up in situations where users have LSE implicitly selected
while no crystal is available on board, leading to non functional
LPTIM.
To avoid this situation, makes LSI clock, which is always available
(since internal to the SoC), the default LPTIM source clock.
Then, default case will be functional. Users will then be able to
select LSE if needed.

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.
