Subject: [PATCH 1/3] net: ethernet: wiznet: add CONFIG_PM_SLEEP to
 suspend/resume functions

Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following
build warning when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when
the CONFIG_PM_SLEEP is enabled.

drivers/net/ethernet/wiznet/w5100.c:758:12: warning: 'w5100_suspend' defined but not used [-Wunused-function]
drivers/net/ethernet/wiznet/w5100.c:773:12: warning: 'w5100_resume' defined but not used [-Wunused-function]
drivers/net/ethernet/wiznet/w5300.c:670:12: warning: 'w5300_suspend' defined but not used [-Wunused-function]
drivers/net/ethernet/wiznet/w5300.c:685:12: warning: 'w5300_resume' defined but not used [-Wunused-function]
