David Nadlinger 720838a23e gateware/suservo: Avoid magic number for activation delay width 
Mostly for documentation purposes; 8 bits ought to be enough for
everyone.

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

suservo: cleanup, straighten out timing

suservo: dds cs polarity

suservo: simplify pipeline

suservo: drop unused eem names

suservo: decouple adc SR from IIR

suservo: expand coredevice layer

suservo: start the correct stage

suservo: actually load ctrl

suservo: refactor/tweak adc timing

suservo: implement cpld and dds init
