arm64: zynqmp: Enable IIO hwmon sensors

Wire PS ams sensors with hwmon sensors to have quick way how to read
information about chip from sensors tools and others(gkrellm).
Using iio-hwmon is deprecated but still valid option how to do it.
When iio framework is better integrated in standard tools this should be
changed.
