Robert Jördens 347609d765 rtio: auto clear output event data and address 
This is to support channels where variable length
event data is well-defined through zero-padding.
E.g. in the case of `Spline` zero-padding of events naturally
corresponds to low-order knots.

Use timestamp change as trigger. This assumes that writes to the
timestamp register always precede address and data writes.
It does not break support for ganged writes of the same event
timestamp and data/address to multiple channels or
channel-addresses.

whitequark 4df7941a97 runtime: don't attempt to perform writeback if disabled in kernel. 
Otherwise, the startup kernel session hangs.

whitequark cd7527b701 runtime: print trace level log messages to UART during startup. 
There's no way to retrieve them otherwise if the startup kernel
hangs.
