net: sfp: rework upstream interface
The current upstream interface is an all-or-nothing, which is sub-optimal for future changes, as it doesn't allow the upstream driver to prepare for the SFP module becoming available, as it is at boot. Switch to a find-sfp-bus, add-upstream, del-upstream, put-sfp-bus interface structure instead, which allows the upstream driver to prepare for a module being available as soon as add-upstream is called.
