rt_cpu: disable PLL verbose mode by default (output on UART is blocking and greatly slows down LDPC port calibration in the WR Switch)

In case we are using the WR_NIC_CPU option we redirect ARP & ICMP to
external fabric (controlled by NIC driver on host CPU).
We have also add this option to Kconfig and update the wrnic_defconfig
used by wr-starting-kit

LLDP a vendor-neutral link layer protocol used by network devices
for advertising their identity, capabilities, and neighbors.
Implements a transmit-only nodes, the node only transmit periodically
and doesn't process any LLDPUD.

This introduces "mode abscal", that forces a gm-lookalike mode in the
node, to send sync once per second. See "absolute calibration" document
by Peter Jansweijer from nikhef. The option is Kconfig'd, but on by
default.

This commit adds a tool to send out, through ethernet, a complete log of
DAC values for the main oscillator. It allows to see if there are
oscillations (and there currently are) and what happens when tracking
is lost and recovered.

To activate the feature

  * add CONFIG_DAC_LOG (depends on CONFIG_DEVELOPER)

  * activate on the console: "daclog <ipaddr> <macaddr>"

  * collect data on your target host

     netcat -u -l -p 1050  | od -An -t u2 -v -w2 --endian=big > daclog.txt

  * stop it when done, on the console: "daclog off"

this is a software part of new (additional) diagnostics for WR PTP Core.
It allows to access diagnostics values through WB registers (e.g. PCI
bus). This is useful for integration of WR with CERN cotrols infrastructure,
such as FESA. It allows the host machine (of SPEC/SVEC/etc) to easily
access information about the health of WR PTP Core.

I spits a number of warnings, and we are not simulating snmp anyways.
Better avoiding the warning than fixing

This simplifies, in a way.  Otherwise, we'd need to make most

If !CONFIG_SYSLOG, usual verbose output is printed to console.

If CONFIG_SYSLOG, you can send the latency error problems to syslog.
The node sends to syslog only the number of lost frames (FIX THIS)
and the latency if it's more than twice the current running average.
such an average is on 8 samples, so it moves quickly.

Now the default for configurations that do not select peer-delay
is to not even build peer-delay code. This provides for that, and
adds two configurations for peer-delay operation.

If pdelay is selected, e2e is built as well, but selection is currently
only at build time. This will be fixed later.

Without this, after the first build of wrpc-sw the ppsi
configuration was never changed.

So if you built e.g. "gsi_defconfig" and then reconfigure
for "gsi_pdelay_defconfig" you'll get no pdelay in there.

For me, and the next maintainers of ppsi, the new configuration option
CONFIG_PPSI_FORCE_CONFIG can be unset in order to test with personale
changes in ppsi configuration.

The new config tools are more picky. We got:

   Kconfig:22:warning: defaults for choice values not supported

and

  warning: (WR_SWITCH) selects UART which has unmet direct dependencies
             (DEVELOPER && EMBEDDED_NODE)

The latter is fixed adding WR_SWITCH in the dependencies. The former
is worked-around by using "IS_XINT" and friends in "choice", and
then "XINT" replicates the "IS_" choice.  I dislike it, because it's
repetition, but we really need CONFIG_PRINTF_XINT and friends in

The "community" string is public. We have tree items only: the host
name, the date and uptime.

The code is designed to make it simple any addition. But we only have
snmpget support, not snmpwak (i.e. "get next" query).

This is run on an host build (CONFIG_HOST_PROCESS) where the time and
date are not related to the real world:
