iio: imu: inv_mpu6050: new timestamp mechanism

Check validity of interrupt timestamps by computing time between
2 interrupts. If it matches the chip frequency modulo 4%, it is
used as the data timestamp and also for estimating the chip
frequency measured from the system. Otherwise timestamp is
computed using the estimated chip frequency.
