This commit simplifies the Device Tree configuration by using
the new helpers introduced in #30536.
In particular:
- get bus devices with DEVICE_DT_GET
- get SPI information with SPI_CONFIG_DT_INST

Currently there is no way to distinguish between a caller
explicitly asking for a semaphore with a limit that
happens to be `UINT_MAX` and a semaphore that just
has a limit "as large as possible".
Add `K_SEM_MAX_LIMIT`, currently defined to `UINT_MAX`, and akin
to `K_FOREVER` versus just passing some very large wait time.
In addition, the `k_sem_*` APIs were type-confused, where
the internal data structure was `uint32_t`, but the APIs took
and returned `unsigned int`. This changes the underlying data
structure to also use `unsigned int`, as changing the APIs
would be a (potentially) breaking change.
These changes are backwards-compatible, but it is strongly suggested
to take a quick scan for `k_sem_init` and `K_SEM_DEFINE` calls with
`UINT_MAX` (or `UINT32_MAX`) and replace them with `K_SEM_MAX_LIMIT`
where appropriate.

The ',' character was used as line terminator instead of ';'
in SPI routines. The three affected drivers were not showing
any issue, but the typo is fixed for clarity.

Make this driver multi-instance and use the new API.
Notes for sensorhub mode:
In case of multiples devices it is possible that some of them
has i2c slaves attached to it (sensorhub mode) but not the
others. Since the driver is configured in the same way for
all the instances (CONFIG_SENSORHUB=y), the routine that initialize
the sensorhub part does not fail anymore in case no slaves
are found for a particular instance. Instead, those non-sensorhub
driver instances will set the shub_inited flag to false and
will totally ignore the feature.
Notes for triggers:
In case of multiples devices the device pin the interrupt wire is
attached to can be different (INT1 or INT2 pin). So, this
information has been moved in DTS and then stored in the
specific instance config structure.
Currently the driver is able to handle a sngle interrupt line
at a time attached to either INT1 or INT2.
MOreover, the interrupt initialization for a driver instance proceed
only if the drdy has been configured in its DT, else it returns ok.

The IIS2ICLX is a high-accuracy. ultra-low noise, low-power
two-axis linear accelerometer which can be interfaced through
either I2C or SPI bus.
Its high accuracy, stability over temperature and repeatability
make IIS2ICLX particularly suitable for inclination measurement
for industrial applications (inclinometers).

This driver is based on stmemsc i/f v1.03.
