[PATCH v2] doc: add deprecation notice for iavf devarg auto reconfig

[Thomas Monjalon]

> > The `auto_reconfig` devarg in the iavf driver is enabled by default and the
> > case for ever disabling it is weak. When disabled, it means the user is
> > requesting the driver not to restore settings (unicast/multicast
> > promiscuous modes) when recovering from a reset. The use case where this
> > might be desired is during a VF initiated reset where the user initiates
> > the reset and wants the VF brought back up in an untouched state. That
> > scenario can be facilitated by extending the `rte_pmd_iavf_reinit` API
> > rather than relying on this devarg, so it should be safe to remove the
> > devarg.
