Modify the sof monotonic boot timestamp logic. Boot time stamp difference between two frames should not change, it should be same as qtime csid time stamp difference. So modified logic to give proper boot time stamp with no difference in the successive frames, the difference of sof time stamp taken from qtime stamp value. Delayed IRQ handling can lead to torn read of timestamp register (LSB from nth frame and MSB from n+1th frame). This change tries to detect torn read cases and corrects timestamp close to the actual value.
