Device IDs for AD3542R and AD3552R were swapped leading to unintended
collection of DAC output ranges being used for each design.
Change device ID values so they are correct for each DAC chip.

A user has reported that the IDs were wrong and the output ranges were not ok.
Also, the dt-doc and the driver require the adi,output-range-microvolt property
for ad3542r but not for ad3552r, which could cause actual ad3552r probing to
fail if the device node did not have that property.
It's not clear from datasheet if setting the output range is really required for
ad3542r.
Was once better at sending patches. Hope I get used to it again :)
Thanks

Applied to the fixes-togreg branch of iio.git and marked for stable.
Thanks,
