Robert Jördens 6cdb96c5e0 rtio: add support for latency compensation in phy 
* if multiple RTIO channels influence the same data stream and physical
output channel (see SAWG) differential latency needs to be compensated
* this is a NOP for phys with zero delay (default)
* if delay==1, it adds one timestamp-wide register
* if delay >1, it adds one adder and one register
* latency compensation using (~10-50 deep) delay lines is about as
expensive as a single adder+register but very tedious to implement
