ice: introduce VF port representor
Port representor is used to manage VF from host side. To allow
it each created representor registers netdevice with random hw
address. Also devlink port is created for all representors.
Port representor name is created based on switch id or managed
by devlink core if devlink port was registered with success.
Open and stop ndo ops are implemented to allow managing the VF
link state. Link state is tracked in VF struct.
Struct ice_netdev_priv is extended by pointer to representor
field. This is needed to get correct representor from netdev
struct mostly used in ndo calls.
Implement helper functions to check if given netdev is netdev of
port representor (ice_is_port_repr_netdev) and to get representor
from netdev (ice_netdev_to_repr).
As driver mostly will create or destroy port representors on all
VFs instead of on single one, write functions to add and remove
representor for each VF.
Representor struct contains pointer to source VSI, which is VSI
configured on VF, backpointer to VF, backpointer to netdev,
q_vector pointer and metadata_dst which will be used in data path.
