The ad2s90 driver currently sets some spi settings (max_speed_hz and
mode) at ad2s90_probe. This should, instead, be handled via device tree.
This patch removes these configurations from the probe function.
Note: The way in which the mentioned spi settings need to be specified
on the ad2s90's node of a device tree will be documented in the future
patch "dt-bindings:iio:resolver: Add docs for ad2s90".
