net/sfc: let driver-internal flows use VF representor action

In the case of VF <--> VF representor pairs, these flows can
only collect VF traffic, so let them use generic flow action
PORT_REPRESENTOR, as part of re-using generic flow mechanism.

Currently, it does not allow to access VF representors since
they have no unique HW logical ports (m-ports). They all sit
on the same (representor proxy) m-port, while demultiplexing
of traffic uses ingress (VF) m-port value in packet metadata.
Traffic from arbitrary sources cannot be identified this way.
But, for VF traffic, it should be right to make an exception.

net/sfc: maintain controller to EFX interface mapping

Newer hardware may have arbitrarily complex controller configurations,
and for this reason the mapping has been made dynamic: it is represented
with a dynamic array that is indexed by controller numbers and each
element contains an EFX interface number. Since the number of controllers
is expected to be small, this approach should not hurt the performance.

net/sfc: support concept of switch domains/ports

A later patch will add support for RTE flow action PORT_ID
to MAE backend. The driver has to ensure that such actions
refer to RTE ethdev instances deployed on top of the same
physical device. Also, the driver needs a means to find
sibling RTE ethdev instances when parsing such actions.

In order to solve these problems, add a switch infrastructure
which allocates switch domains based on persistence of device
serial number string across switch ports included in a domain.
Explain mapping between RTE switch port IDs and MAE endpoints.
