devlink: Introduce devlink port flavour virtual

Currently mlx5 PCI PF and VF devlink devices register their ports as physical port in non-representors mode. Introduce a new port flavour as virtual so that virtual devices can register 'virtual' flavour to make it more clear to users. An example of one PCI PF and 2 PCI virtual functions, each having one devlink port. $ devlink port show pci/0000:06:00.0/1: type eth netdev ens2f0 flavour physical port 0 pci/0000:06:00.2/1: type eth netdev ens2f2 flavour virtual port 0 pci/0000:06:00.3/1: type eth netdev ens2f3 flavour virtual port 0
