the pp_printf_defconfig was the trial version for pp_pritnf as an
alternative to mprintf, so it is not needed any more.  All other
defconfig were working already, but I'd better regenerate them with
the current defaults.

mprintf is of uncertain copyright status, and that's why
we added pp_printf (actually, that's why I picked pp_printf
fro ptp-proposal and made it a standalone thing).

Now that everyone involved confirms pp_printf is well tested,
let's remove mprintf.  We still accept mprintf in the callers,
because the name is used by our ptp-noposix submodule, and I'm
sure people has it in their fingers and it will appear again.

The ppsi submodule (which is being cleaned up) now has a separate
structure for whiterabbit-specific data associated to the port. This
commit includes such change and adapts its own structures accordingly.

The ppsi subproject now builds pp_printf by default, so the Makefile here
passes ~CONFIG_NO_PRINTF=y". Also, assign_TimeInternal() is not there
any more because it is just an assignment.

The minic driver reads the TX timestamp from the device after sending.
Unfortunately, it only waited for the data to be enqueued to be sent.
Sometimes this lead to a race condition where the old TX stamp was read.

As a result, the PTP calculation goes wrong by as much as an entire second.
When in track_phase, this manifests as a bad phase offset sent to softpll.
The softpll takes years to reach that phase offset, so it is always busy.
Thus the clock drifts further and further away, never correcting.
