When WR PTP Core is set in GrandMaster mode it aligns its nanosecond
counter to 1-PPS and 10MHz coming from external source. When user wants
to set seconds counter to a desired value (with _time set_ command), the
nanosecond counter was also set (zeroed) causing additional (random)
offset to the external source. The commit adds _time setsec_ and _time
setnsec_ for setting only seconds or nanoseconds counter without
affecting the other one. Now, when user wants to set current time on a
GrandMaster Node he has to call _time setsec_ command after _mode gm_

Conflicts:
	wrc_main.c

when Etherbone support is turned off ARP/ICMP/.. (in general all non-PTP)
traffic has to go into external fabric interface of WRPC because it won't be
handled by WRPC software

We don't want to call the real printf, which brings in the whole of
newlib, but it sometimes happen. So let's diagnose the problem
immediately rather than letting users wonder what is wrong with the
size.

Similarly, if building under ppsi, ensure we are not calling libgcc
division functions: any 64-bit division my be done with __div64_32
offered by ppsi/lib (copied from the kernel).

This reverts commit 0bcbe429

.

Now that we are able to check for bogus printf calls, don't define the
name any more (ptp-noposix defines it anyways, but let's not do it
when building with ppsi, so the code explicitly calls pp_printf (or
mprintf, which will remain as an alias until we get rid of
ptp-noposix).

This reads to stdout, in binary format. With "-v" it prints text and
scans the bus too. The examples here below use the same card (and same

The command is not documented, and it looks like is not useful either
(I understand it has been useful when setting up the init area initially)

Cesar Prados noted that if you boot w1 directly, not passing through
sockitowm, w1 was not working.  I always run sockitowm because I have
it in the lm32 code that starts every time I load the fpga.

This fixes the missing clock divisor.
