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.
