rtio: add one register level for rio and rio_phy resets
...
* This should give Vivado some wiggle room during PnR.
* It needs three new clock domains which is ugly. But since
AsyncResetSynchronizer can only drive clock domains resets directly
there seems to be no other way to add one register level currently.

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
