ice: Add driver support for firmware changes for LAG
Add the defines, fields, and detection code for FW support of LAG for
SRIOV. Also exposes some previously static functions to allow access
in the lag code.
Clean up code that is unused or not needed for LAG support. Also add
an ordered workqueue for processing LAG events.
