sfc: attach/detach EF100 representors along with their owning PF

Since representors piggy-back on the PF's queues for TX, they can
only accept new TXes while the PF is up. Thus, any operation which
detaches the PF must first detach all its VFreps.

sfc: Add a PROBED state for EF100 VDPA use.

For VDPA we need to tear down the driver to the point where it
has various control channels like MCDI, but it no longer has
a network device. This adds a state corresponding to
that mode that will be used when VDPA support is added.

sfc: Split STATE_READY in to STATE_NET_DOWN and STATE_NET_UP.

This patch splits the READY state in to NET_UP and NET_DOWN. This
is to prepare for future work to delay resource allocation until
interface up so that we can use resources more efficiently in
SRIOV environments, and also to lay the ground work for an extra
PROBED state where we don't create a network interface,
for VDPA operation.

than efx_mcdi_set_mac().
