iio: adis16475: do not directly change spi 'max_speed_hz'
With commit
3ba10e37371d ("iio: adis: add burst_max_speed_hz variable"), we
just need to define 'burst_max_speed_hz' and the adis core will take
care of setting up the spi transfers for burst mode. Hence, we fix
a potential race with the spi core where we could be left with an
invalid 'max_speed_hz'.
