iio: imu: adis16475: Re-define ADIS16475_DATA
Re-define ADIS16475_DATA such that it takes _burst_max_len, _burst_max_speed_hz and _has_fifo as parameters. Also, do a preparatory rename operation for ADIS16475_BURST32_MAX_DATA to ADIS16475_BURST32_MAX_DATA_NO_TS32 to be able to differentiate in the future between devices which are using 16-bit or 32-bit timestamp size in burst mode.
