Be mindful of the increase in runtime generated by the more performant
Linux MHU driver.

Signed-off-by: Ambroise Vincent <ambroise.vincent@arm.com>

This allows to work around degraded network performance in specific
scenarios when using the proper MHUv3 driver on Linux.

The degraded scenarios were:
  * tcp upload from Safety Island cluster 1 and 2 to Primary Compute
  * udp download to Safety Island cluster 1 and 2 from Primary Compute

This allows the tcp upload scenario to reach 160Mbps, from 25Mbps
without pinning.

Remove the previous patch on the MHUv2 driver to make it work with
MHUv3.

Update all references from MHUv2 to MHUv3.

Increase the timeout for iperf tests. The switch to the MHUv3 driver
leads to increased network performance between the Primary Compute and
the Safety Island. The iperf/zperf tests take the same time from the
point of view of the simulated components, and they are now transferring
more data in the same amount of simulated time, which leads to an
increase in test time from the point of view of the Host.
zperf doesn't allow for floating point arguments, so setting a test time
of less than a second is not an option.

This patch will add support for Itnter Safety Island clusters

Add support for MBOX MHUv3 driver to support Inter Safety Island
clusters communication implementation. Inter SI clusters communication
will be based on IPC RPMsg Static Vrings that use MBOX APIs to
send/receive events.

Current HIPC implementation is based on the IPM MHUv3 driver. Use MBOX
MHUv3 driver for HIPC implementation to have a single driver for MHUv3.

Use Openvswitch and VLANs setup for the Kronos network.

Change zephyr HIPC overlays to include the Kconfig parameter
that enables the VLAN network handling.

Rework the systemd network configuration files to unify baremetal
and virtualization profiles.

Introduce a new systemd service that brings up the Openvswitch
bridges at startup, Openvswitch remembers the configuration across
the reboots, so this service will run every startup but will create
the bridges only the first time.

Introduce a systemd drop-in file for the xendomains service
that introduces a dependency between the above newly introduced
service and the xendomains one, only under virtualization profile.

Modify the domu-package variables to use the Xen scripts for
openvswitch that adds the guests port into the bridges, while
there, add a newline to the DOMU{1,2}_EXTRA variable to let it land
on the created configuration file as end of file blank line.

Modify fvp_rd_kronos_safety_island_c0_actuation.conf board to
include a Kconfig parameter for the VLAN id of the second interface
and while there, disable the net "config" library module since the
application is already setting the network configuration by itself.

Currently the kronos-network-conf.bb recipe uses the same folder
for S and WORKDIR, this is giving some issues because the WORKDIR
is not cleaned and changes like remove of files are not performed
and will end up in the deployed image.

So separate S and WORKDIR to fix the issue, while there, suppress
a warning for the licence file.

The OEQA SSH runner kills processes that do not output anything after a
timeout period (default 300s). If this timeout occurs, the exit code
will be either 255 (if the SSH process exits cleanly) or 0 (if the SSH
process does not terminate within 5s and has to be killed).

The BATS tests (executed by ptest-runner) contain a lengthly period of
silence while waiting for the DomUs to boot (>300s) so increase the
timeout.
