Fix the following compile warning:

drivers/net/ethernet/microchip/lan743x_main.c:2964:12: warning: lan743x_pm_suspend defined but not used [-Wunused-function]
 static int lan743x_pm_suspend(struct device *dev)
drivers/net/ethernet/microchip/lan743x_main.c:2987:12: warning: lan743x_pm_resume defined but not used [-Wunused-function]
 static int lan743x_pm_resume(struct device *dev)
