Robert Jördens 87d3ac9d25 suservo: swap transfer function parametrization
The integrator is now parametrized through its gain and not the PI
corner frequency. The integrator gain limit is given in absolute gain
units and not relative to the proportional gain.

Robert Jördens 307cd07b9d suservo: lots of gateware/ runtime changes
tested/validated:

* servo enable/disable
* dds interface, timing, io_update, mask_nu
* channel control (en_out, en_iir, profile)
* profile configuration (coefficients, delays, offsets, channel)
* adc timings and waveforms measured
* asf state readback
* adc readback

individual changes below:

suservo: correct rtio readback

suservo: example, device_db [wip]

suservo: change rtio channel layout

suservo: mem ports in rio domain

suservo: sck clocked from rio_phy
