occheung 2613df692b 4410-4412: fix dds signal spec citation
* cite wiki instead of datasheets for frequency range, as the rest of the signal chain has low response for low frequency
* cite wiki instead of ad9912 datasheet for frequency resolution, see the ad9912 design bug on wiki

occheung 011d63f3eb 4410: modify ram example
* Use `prepare()` to init the arrays, would be great if the value can be prepared there. However, the type check was not happy about it.
* Separate RAM configuration into a separate function
* Separate DDS init, digital attenuation & switch config in an init function
* Use `dds.set()`. It is supposed to look simple.

All these are to avoid repeating the long code in the coming RAM+SYNC example.

occheung b657e0fea5 4410-4412: clarify nominal power
The same figure can be found in sinara issue 354 / urukul issue 3, and it was meant to be an empirical limit for low frequency RF outputs.
