pd: revert slow traces in PD code

The commit 4ba7a15 has modified the traces resulting in a far larger overhead
(mainly due to %T doing dozen? of 64-bit divisions which is an expensive
operation on a Cortex-M0)
as a result the code is now missing communication deadlines.
for lack of a better solution, revert the modification is this file.
