Registers driver with pm_device_driver_init(); implements TURN_ON,

The DHT driver incorrectly assumes all sensor instances are the same
type as the first instance (dht@0). The data parsing logic uses a
hardcoded check of the devicetree property for instance 0, which
causes incorrect readings when different sensor models (e.g., DHT11
and DHT22) are used together.
This change stores the model type in each per-instance config struct
during initialization. The data parsing logic is updated to use this
per-instance flag, ensuring each sensor is handled correctly
according to its specific model.

Changed the format of the run time data to Q26.6 and adjusted the
assignment of val1 and val2 accordingly.

While it would likely not directly cause issues with the current
implementation, the logic of turning off the sensor should be to
actually reset the flags, not to toggle them.

a new DT property, fifo-mode-sel, which may be set to one of the
following values:
- 0x0 # 1x Accelerometer @12bit and 1x temperature @12bit samples
- 0x1 # 1x Accelerometer @16bit sample
- 0x2 # 2x Accelerometer @8bit samples (previous and current)

Remove logically dead if and else-if conditions as shown by the static
analysis, replacing with the else statement.
When data_opt is assigned to the MIN of fifo_wmark_cfg and fifo_full_cfg,
both those variables will be non-NULL as an earlier condition ensures the
function returns if either one of the variables is NULL before assigning
to data_opt.

Add RTIO async and RTIO stream functionalities that enables,
among all the other things, the sensor data streaming from FIFO.
RTIO stream supports following triggers:
- SENSOR_TRIG_FIFO_WATERMARK
- SENSOR_TRIG_FIFO_FULL
- SENSOR_TRIG_DATA_READY
Following FIFO parameters has to be defined in device tree to
correctly stream sensor data:
- fifo-watermark
- accel-fifo-batch-rate
Currently the driver can decode FIFO content with Accelerometer
16-bit samples.

A recent change 9eeb60c improperly removed a critical line in the driver.
This commit replaces that line and moves an irq_lock to above any pin
value manipulation since the timing is sensitive with the DHT protocol.
This should also fix the timing issue 9eeb60c attempted to fix.

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.
