Read and send real IMU frequency from IMU register

[gauteh]

Case#: 00179461
Subject: LSM6DSOX/ISM330DHCX: real sample rate lower than expected in FIFO mode
Description:
Dear Gaute,

ODR specified in the datasheet refers to typical value, so the actual ODR may differ from typical value.

You can get actual ODR of the device following equation "ODRactual" stated in section 6.4 Timestamp of both AN for LSM6DSOX and ISM330DHCX:

Let me know if you have any other questions.

Kind regards,
