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 order to have a more similar wrpc-sw using wrnic_defconfig or using
spec_defconfig

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

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.

Keep assert enabled only for devel_build_test_defconfig

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.

The configuration is not called *_defconfig, because we can't just
build it in ./MAKEALL -- we need ppsi to be built with a different
configuration, and this is not autodetected yet (but building from a fresh
clone works).

Also, this changes how to mac address is retrieved in patching pfilter
rules. I'd better use format_mac(get_mac) for the verbose message,
so get_mac is also the source for patching the rules.

register and get_mac/set_mac are guaranteed to be in-sync.

This commit adds the possibility to build an init command in the
binary.  It can be useful to install a number of nodes with a special
configuration, without the need to reach the shell and/or eeprom of
each one.

This is useful, for example, to pass syslog configuration
or the (yet to be implemented) definition of multiple vlans for
etherbone and the wr fabric (frame classes 7 and 6 f the packet
filter). Moreover, I personally love to load a master or slave node
for testing without interacting with the node (or changing the flash
over and over).

This commit also makes reading of commands from storage an optional
feature, but only in the advanced/developer options. Thus, you can
build a wrpc that uses the build-time init commands, or the
flash-stored init commands, both or none of them.

Size effects:
     * no effect if you keep the defaults (no build-time init, flash init)
     * +248 bytes (+ the command itself) if you enable build-time init
     * -1696 bytes if you remove flash-based init (discouraged)

This changes the pfilter rule-set, to make it ready for vlan addition.
Moreover, it removes the choice between three rule-sets and uses one
that works for everyone (we'll add the vlan option later on).

Moreover, we prepare for the option of peer-delay PTP and UDP-based PTP.

As a side effect, one Kconfig option is removed.

We know for sure that what goes to the "streamer" protocol
is re-checked, so the streamer can get some "everything else", exactly
like the 7S wr-nic (that sends to the host everything unused).

This is the current rule set:

     - everything tagged is dropped
     - CPU: arp broadcast, not unicast (i.e. requests only).
     - CPU: PTP ethtype. Any mac address.
     - CPU: ICMP unicast, not broadcast.
     - CPU: UDP (uni/multicast), ports  bootpc, ptp-event, ptp-general.
     - Etherbone (class 7): UDP (uni/multicast) and port 0xebd0
     - Other fabric (class 6): anything not Etherbone (inverted class 7 bit)

This counts up to 28 rules. We have 4 more rules available and we may
add options, either at build time or run time to add udp ports or
other ethertypes.  Or not...

2 caveats:

  - frames for the CPU will have class bits 0x41 instead of 0x01, because
  everything not etherbone will receive bit 6. This is not a problem, as
  the CPU is not checking the class bits.

  - the wr-nic gateware, when using this new sw code base, must be
  changed to use classes 6 and 7 like everybody else, not classes 7
  and 5.

This removes TRACE_DEV(), turning it into pll_verbose() and wrc_verbose().

The functions are enabled and disabled by kconfig, with defaults matching
the previous behaviour.

So nothing changes, but the binary is smaller because the previous
wrc_debug_printf() was silent because of a run-time conditional
(though hardwired false at build time). The condional is now at build
time.  We save around 2k, between strings and calling code, in
all wrc builds (nothing is saved in wrs, which is verbose by default,
nor in devel_build_test_defconfig where all verbose options are on)).

This configuration includes all developer options, so we are sure that
./MAKEALL is build-testing all the code (excluding the very-reduced
pp_printf implementations).
