A 16-bit value built using byte shifts and ORs from a given
couple of lsb and msb bytes will result to be the same on both
little-endian and big-endian architectures, e.g.
uint8_t lsb, msb;
int16_t val;
/* val is the same number on both le and be archs, but has
different layout in memory */
val = (msb << 8) | lsb;
All the xyz_raw_get() APIs of stmemsc sensor module build the sensor
data using the above method and DO NOT hence require (it actually leads
to wrong values on big-endian machines) to use any le/be swap routines,
such as sys_le16_to_cpu().

In lis2dux12_set_odr(), the call to stmemsc module lis2dux12_mode_set()
API is done with the .fs field left uninitialized, so setting the
underlying device regs in an unproper way.

Return to sensor_api i/f the temperature in Celsius instead
of the register raw value in LSB.

The current implementation assumes that sensor odr and range are
always configured in the Device Tree at compile time which might
not be the case.
Instead, application can set odr and range either at compile time
through the DT or using SENSOR_ATTR_SAMPLING_FREQUENCY and
SENSOR_ATTR_FULL_SCALE attributes at runtime, so each driver instance
must keep trace of the latest values set and use them in the sensor
APIs which require them (e.g. lis2dux12_mode_set).

When setting the full scale through SENSOR_ATTR_FULL_SCALE the
driver must convert the g value (i.e. one of 2g/4g/8g/16g) to
the corrispondent sensor fs raw value.
