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.
