My students are using a disco_l475_iot1 board with HTS221 sensor.
When logging is enabled, the following log message is always emitted:
"HTS221: Cannot enable trigger without drdy-gpios"
This message is confusing to my students as they are not using the
HTS221 sensor in their projects. However since HTS221 is enabled in
the devicetree it gets initialized on boot and the log message
appears.
It doesn't seem necessary to tell people that they haven't enabled
CONFIG_HTS221_TRIGGER at log level INF. I'd be amenable to changing
this to LOG_DBG, but I don't think it needs to exist at all.

Add the possibility to fetch specific sensor channels independently,
either pressure data with SENSOR_CHAN_PRESS or temperature data
with SENSOR_CHAN_AMBIENT_TEMP.
Additionally, the option to fetch both channels simultaneously remains
available using SENSOR_CHAN_ALL, thus not breaking any samples.

This add basic support for the STM32 Digital Temperature Sensor found
notably on the STM32H7 series. It work in interrupt mode and support
basic power device management.
It does not support the more advanced features like using the
temperature threshold, triggers from LPTIM or using the LSE clock in
during sleep or stop.

The STM32 temperature, battery and voltage reference sensors needs to
write the ADC common registers to enable the corresponding ADC features.
For that we need to ensure that the ADC is not suspended by using the
pm_device_runtime_get/put methods.

The temperature being computed using a float variable, use
sensor_value_from_float() instead of sensor_value_from_double(). This
saves some flash.

Previous value just activated the ability to trigger for both edges,
without (de)-activating the gpio. This caused an assrtion error in GPIO.h.

The vbat driver requires the adc node to be enabled:
```c
.adc = DEVICE_DT_GET(DT_INST_IO_CHANNELS_CTLR(inst))
```
Update its Kconfig to depend on `DT_HAS_ST_STM32_ADC_ENABLED`,
which is the `"st,stm32-adc"` compat that all ST ADC bindings
include, this will guarantee that at least one ADC node is
enabled, but not necessarily the ADC used by the vbat node.
To make sure that it at least compiles, we init the `adc`
pointer only if the specified ADC node is enabled, otherwise
it will points to `NULL`.
Finally, check if the `adc` points to `NULL` in
`stm32_vbat_init`. We are not relying on the existing
`device_is_ready` check because `DEVICE_DT_GET` will not
return `NULL` if the ADC is enabled. `adc == NULL` means
that the ADC node is not enabled in the devicetree.

When a sensor that depends on an ADC is enabled in devicetree, enable
the ADC subsystem. ADC is roughly equivalent to a bus for these sensors
(the mechanism through which data is transferred), which had the same
conversion applied in #48707.
The same benefits apply here, namely removing the need for the following
pattern in board `.kconfig` files:
```
configdefault ADC
default y if SENSOR
```

The val2 calculation was done using (1000000 / 40960) as
multiplying factor, which was sometimes leading to a
int32 overflow. So, let's use the equivalent (but smaller)
(3125 / 128).

Instead of using floating point operations to compute the vref voltage,
it is possible to use the sensor_value_from_milli() function.
On a STM32G0, this saves 130 bytes of flash, excluding the FP library
needed on a FPU less MCU.

Instead of using floating point operations to compute the vbat voltage,
it is possible to do the computation using 32-bit variables by
reordering operations and using the sensor_value_from_milli() function.

needed on a FPU less MCU.

Make use of sensor_ug_to_ms2() and sensor_10udegrees_to_rad() APIs
to convert from raw values into proper units (i.e. m/s^2 for accel
and rad/s for gyro). It also improves measurement precision.

Since the interrupt state of the IA bit (interrupt source register) is
checked, it needs to be read out everytime, not only on latching.
