iio: pressure: dps310: Adjust Timeout Settings
The DPS310 sensor chip has been encountering intermittent errors while reading the sensor device across various system designs. This issue causes the chip to become "stuck," preventing the indication of "ready" status for pressure and temperature measurements in the MEAS_CFG register. To address this issue, this commit fixes the timeout settings to improve sensor stability: - After sending a reset command to the chip, the timeout has been extended from 2.5 ms to 15 ms, aligning with the DPS310 specification. - The read timeout value of the MEAS_CFG register has been adjusted from 20ms to 30ms to match the specification.
