This examples shows how to use the AD4114 ADC on a
stm32f3_disco board.
As the AD4114 is a 24bits ADC resolution we need to be able
to pass 32bits buffer to get the samples.
CONFIG_SEQUENCE_RESOLUTION is set to 12 instead of 24, and the
gain zephyr,vref-mv is adapted to avoid overflows using the
exisiting adc_raw_to_millivolts function.

The AD4114 is a low power, low noise, 24-bit, sigma-delta ADC.
This driver allows to use it with the Zephyr ADC API. It uses
the continuous acquisition ADC feature.
This ADC allows many configutations, but this driver uses it as the
most generic way :
- each can channel can be enable or disable using the device
tree configuration
- configure two setups (one for unipolar inputs, one for bipolar inputs)
- use an external clock

1. Temperature Interface
According to BMI08x datasheet, temperature reading
requires both MSB and LSB bytes to be read and
processed correctly.
Temp data processing should follow the formula:
Temp in °C = (temp_msb * 8) + (temp_lsb / 32)
This patch implements the correct reading
sequence and calculation method as specified
in the datasheet.
2. Trigger Setting
Previously we set handler and then trigger struct.
However under some situation, as long as we set
the handler, we get into ISR immediately and never
set trigger struct.
I simply changed the sequence.
Testing:
- Verified temperature readings match datasheet
- Tested on stm32f407igh board with BMI08x sensor
Fixes: #82375

`sensor_sample_fetch` is documented as blocking until the fetch
operation is complete. Update the implementation so that this is true.
Since the fetch operation now blocks, there is no need for the data
ready trigger.

When configuring the device to run in one-shot mode, the AS6212 requires
the sleep mode bit to be set. From the datasheet:
```
The sleep mode is activated by setting the bit SM in the configuration
register to 1. This shuts the device down immediately and reduces the
power consumption to a minimum value.
Entering the sleep mode will take some time (120 ms maximum) and the
first conversion after the sleep mode has been entered takes longer than
the values specified in Figure 7. It is therefore recommended when
entering sleep mode to trigger a single shot conversion at the same
time. After 150 ms (max), the device has then entered the sleep mode and
subsequent conversion times are as specified in Figure 7.
```

This commit introduces a new Sensor Clock API, enabling the retrieval
of cycle counts and conversion to nanoseconds based on the system or
external clock. The API includes:
- `sensor_clock_get_cycles()` to get the current cycle count from the
sensor clock.
- `sensor_clock_cycles_to_ns()` to convert cycles to nanoseconds using
the clock's frequency.
The implementation supports both system clocks and external clocks
defined in the device tree, making the sensor clock integration more
flexible for various sensor use cases.

Fix incorrect nbytes_to_read calculation in ext2_inode_read() function.
Previously nbytes_to_read was decremented by read value which caused
incorrect calculation of bytes to read in subsequent iterations.
Now nbytes_to_read is decremented by to_read value which represents
the actual number of bytes read in current iteration.
This fixes potential data corruption issues when reading files from
ext2 filesystem.
