ice: Implement support for SRIOV VFs across Active/Active bonds

This patch implements the software flows to handle SRIOV VF
communication across an Active/Active link aggregate.  The same
restrictions apply as are in place for the support of Active/Backup
bonds.

- the two interfaces must be on the same NIC
- the FW LLDP engine needs to be disabled
- the DDP package that supports VF LAG must be loaded on device
- the two interfaces must have the same QoS config
- only the first interface added to the bond will have VF support
- the interface with VFs must be in switchdev mode

With the additional requirement of
- the version of the FW on the NIC needs to have VF Active/Active support
This requirement is indicated in the capabilities struct associated
with the NVM loaded on the NIC.

The balancing of traffic between the two interfaces is done on a queue
basis.  Taking the queues allocated to all of the VFs as a whole, one
half of them will be distributed to each interface.  When a link goes
down, then the queues allocated to the down interface will migrate to
the active port.  When the down port comes back up, then the same
queues as were originally assigned there will be moved back.
