As per description of the sys_clock_elapsed() function, "the kernel
will call this with appropriate locking, the driver needs only provide
an instantaneous answer". Remove then the unnecessary locking from the
function, as it only adds an undesirable delay.

After system reset (SETETHRST) interrupt enable register (EIE)
has the default value 0x8010 and global interrupt enable flag (INTIE)
is set. This is not desired and the INTIE flag should be set only at
the end of the initialization.
Disable INTIE flag and set desired interrupts sources in
a single write command just right after system reset.
Resolves: #35091

The controller has several interrupt sources which are signaled
via a single INT pin. Only the interrupt sources that are explicitly
switched on during controller initialization may generate an interrupt
signal. Currently there are only PHY Link Status Change Interrupt
and RX Packet Pending Interrupt enabled. So there is no other reason why
an interrupt can be triggered.
Terminate interrupt handling thread on unknown interrupt
only when debugging, as there are concerns that stopping
thread in the field is going too far.

Deadlock may occur when uart device was put to low power state
while uart_poll_out was in progress. Poll out pends until uarte
is ready to send new byte and it is detected by endtx and txstopped
events being set. When uarte was disabled while poll_out was pending
events were never set and that lead to deadlock. Added a step
in going to low power state in which CPU waits for txstopped event
and only after that uarte peripheral is disabled.

(same considerations as commit 2f01479b)
In a multi-instance driver it may happen that on some h/w
one device should use interrupts and a second device should use
polling mode. So, CONFIG_IIS2ICLX_TRIGGER is not enough to discriminmate
if interrupt inizialization routine should be called or not; the choice
is now based whether the "irq-gpios" property is present in the DT
for that particular instance or not.

When using the uart driver with interrupt and async api
at the same time (instance for interrupt and instance for async),
the transmission complete interrupt was handled in the async
handling section, even when interrupt driven api is used.
This caused transmission to not work properly in interrupt mode.
The fix is to move the interrupt mode handling to the begginning
of the isr. If async mode is used then interrupt mode code
will not be run.

If the label property is missing in a "pwm-leds" compatible DT node
(which is almost always the case), then the device name is now set to
DT_NODE_FULL_NAME instead of "LED_PWM_$inst" previously.
This allows applications to use the DEVICE_DT_NAME macro to retrieve
the device name instead of gessing an arbitrary string.

On Apollo Lake, each GPIO controller has more than 32 pins.
But Zephyr API can only manipulate 32 pins per controller.
So the workaround is to divide each hardware GPIO controller
into 32-pin blocks so each block has a GPIO driver instance.
Compounding to the issue is that there cannot be two device
tree nodes with same register address. So another workaround
is to increment the register addresses by 1 for each block.
So when mapping the address, the lowest 8-bit needs to be
masked to get the actual hardware address.

In case of multi-instance the driver tries to discover whether
there are devices attached to SDx/SCx sensorhub bus. If not it
just turns the shub_inited variable (inside data structure) to false
and skips doing any further sensorhub related action for that
particular IIS2ICLX device instance, regardless the fact that the
macro CONFIG_IIS2ICLC_SENSORHUB is enabled.
Moreover, the info found during the enumeration process for a
particular instance (number and types of attached devices) must be
saved inside the per-instance data structure, so that more than one
IIS2ICLX device can be used as a sensorhub without interfering with
the others.

Resetting the dma_tx.buffer_length after the dma_tx.counter
calculation, instead of before.
We need to reset the buffer_length when the transmission is finished,
but in order to give the correct value to the uart_event_tx struct,
we use the dma_tx.buffer_length in the calculation of the
dma_tx.counter, used for the len of the event (number of bytes sent).
I found this problem, when I wanted to use the uart_event_tx.len for
freeing the used space inside a ring buffer (ring_buf_get_finish),
and it didn't work, I logged the values of the uart_event_tx struct,
and found out it always was 0, because the buffer_length was 0,
and the whole buffer was transmitted (stat.pending_length also 0).
