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.
