A write to the "ctrl_meas" register can cause the sensor to transition
from sleep to normal mode (which is default Kconfig settings). As per
BME280 datasheet, writes to the "config" register in normal mode may be
ignored. This can lead to use BME280_STANDBY_05MS and BME280_FILTER_OFF
instead of the values set by the application. To fix this, write to the
"config" register before "ctrl_meas" in the sensor init function.

Calling sensor API functions on devices not in `PM_DEVICE_STATE_ACTIVE`
is a violation of the PM API. Adding manual checks inside of drivers
complicates the drivers and increases ROM footprint for no additional
benefit.

Since #83575 bma4xx driver relies on RTIO to work. This means that
CONFIG_I2C_RTIO should be defined together with CONFIG_I2C in the
Kconfig, otherwise I2C_DT_IODEV_DEFINE() won't be available at
build time.

Clamp the returned humidity to a non-negative value. This ensure that
the return value is always within the expected range, even if the
calibration parameters are read out incorrectly or corrupted.
This check is applied in the example Bosch driver for the float
conversion case, so there are situations that warrant it.

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

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.

Add support for Bosch bmp390 sensor, the drop in replacement for the
bmp388 with same register but different chip-id. This patch make use
of "bosch_bmp390" or "bosch_bmp388" and set the specific chip-id in a
data->chip-id variable, which then used to check against the register
value.
Additional, manual shift operation had been replaced with ENDIAN safe
macros and calibration values with target variable of int16_t add a
cast for it.
bmp388_spi: read register implementation wrong, fixed it.
tx-buffer must be <addr><dummy><dummy> in order to receive the
register value. Read registers in burst mode and have rx and tx
buffer same spi_buf to avoid clock stop and delay with nrf5.
