ice: changes to the interface with the HW and FW for SRIOV_VF+LAG
Add defines needed for interaction with the FW admin queue interface in relation to supporting LAG and SRIOV VFs interacting. Add code, or make non-static previously static functions, to access the new and changed admin queue calls for LAG.
