ixgbe/base: disable software LPLU implementation for X557 V2

Browse Source 
This patch disables SW LPLU on x557 V2. It also sets the
enter_lplu function pointer to NULL on x557 V2. LPLU will be
implemented in FW for all x557 V2 interfaces. The SW LPLU
implementation must be disabled on V2 to avoid conflicts with
FW. SW LPLU support is still required for x557 V1.
