devlink: Add 'total_vfs' generic device param
NICs are typically configured with total_vfs=0, forcing users to rely
on external tools to enable SR-IOV (a widely used and essential feature).
Add total_vfs parameter to devlink for SR-IOV max VF configurability.
Enables standard kernel tools to manage SR-IOV, addressing the need for
flexible VF configuration.
