jh.Chun a77919b4d3 IMU gyro/accel config fix and README piezo frequency table correction ...

- Add GYRO_CONFIG0/ACCEL_CONFIG0 register setup in imu_read_direct() to fix gyro always returning -32768
- Increase sensor startup delay from 2ms to 80ms for reliable first read
- Put IMU back to sleep after msp? read to save power
- Fix piezo frequency table: swap freq 0/1 values, remove unused freq 5
