Here should be in-ports for tpiu node?

BTW, if upper comment is valid, this means the DT binding doc also
gives wrong example for tpiu node [1].

I tested this patch with upper changing to 'in-ports', etm with perf
mode can work well on DB410c board.

You are right on both counts.

Thanks a lot for the testing. I will fix both the problems.
