Add ADIS1657X family devices compatibles and specify the according
maximum SPI baudrate.
Similarly to other ADIS1650X devices, ADIS1657X supports sync-mode
values [0,2].
Each newly added device has a different angular velocity/linear
acceleration/ delta velocity scale combination, as follows:
Accel dynamic range sensitivity:
- 262144000 LSB/g: ADIS16575
- 52428800 LSB/g: ADIS16576, ADIS16577
Gyro dynamic range sensitivity:
- 2621440 LSB/deg/sec: ADIS1575-2, ADIS1576-2, ADIS1577-2
- 655360 LSB/deg/sec: ADIS1575-3, ADIS1576-3, ADIS1577-3
Delta velocity sensitivity:
- 2^15/100 LSB/m/sec: ADIS16575
- 2^15/125 LSB/m/sec: ADIS16576
- 2^15/400 LSB/m/sec: ADIS16577
Each ADIS1657X device supports FIFO usage and a sample-rate of 4.1KHz,
meanwhile the already existing devices do not support FIFO usage and
have a maximum sample-rate of 2.1KHz.
