a8eace10b3 drivers: sensor: bme280: fix "config" register intialization issue 
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.

f4825033bc sensor: remove PM state checks from API functions 
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.

e661a55044 sensor: bme280: clamp humidity to non-negative 
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.

91e006cb7c sensor: bme280: bme280_wait_until_ready timeout 
Add a timeout to the `bme280_wait_until_ready` loop to ensure that we
never get stuck in this loop even if the bus enters an error condition.

5eb5f3d6a5 sensor: bme280: only configure mode on PM suspend/resume 
Update power management to only start/stop periodic measurements in
`CONFIG_BME280_MODE_NORMAL`, instead of re-initialising the chip
completely.

In `CONFIG_BME280_MODE_FORCED`, there is nothing to do when suspending,
as the sensor is already in its lowest power mode.
