rfnoc: tick_node: Search all nodes for tick rates
The tick_node was trying to find the current tick rate by only querying
active blocks (i.e., blocks that were flagged active-streaming).
However, this is not necessary since we require all blocks to run at the
same tick rate.
In theory, querying active-only ports should be fine, but due to some
idiosyncrasies in our current graph code, connecting a single streamer
to channel 1 (out of 0, 1) would try and get the info from the wrong
port. This is not a fix to the graph code, but the change to tick_node
is also appropriate and is sufficient to fix the "late packets on
channel 1" issue.
This issue would manifest when sending timed packats to channel 1 in
a single-channel streamer. The problem is that it wouldn't be able to
read the correct tick rate.
