net/sfc/base: introduce EVB module for SR-IOV

Implement the framework for Enterprise Virtual Briding (EVB) module.
SR-IOV augments the software virtual switch with NIC capabilities
supported from EVB module.
Further patches will add APIs to create and destroy EVB switching
hierarchy required for SR-IOV and APIs to set vPort properties like MAC,
VLAN etc.
