542a375305 rtio: remove NOP suppression capability
Back when RTIO was driving TTLs, this functionality made it simpler to use by removing some irrelevant underflows.

The same technique is not applicable to DDS and SPI, so the user will have to deal with such underflows.

This patch makes the behavior of RTIO more consistent and the code simpler.
