drivers/net: #ifdef mdio_bus_phy_suspend() and mdio_bus_phy_suspend()
The following build error is emitted by rcutorture builds of v5.12-rc1:
drivers/net/phy/phy_device.c:293:12: warning: ‘mdio_bus_phy_resume’ defined but
not used [-Wunused-function]
drivers/net/phy/phy_device.c:273:12: warning: ‘mdio_bus_phy_suspend’ defined
but not used [-Wunused-function]
The problem is that these functions are only used by SIMPLE_DEV_PM_OPS(),
which creates a dev_pm_ops structure only in CONFIG_PM_SLEEP=y kernels.
Therefore, the mdio_bus_phy_suspend() and mdio_bus_phy_suspend() functions
will be used only in CONFIG_PM_SLEEP=y kernels. This commit therefore
wraps them in #ifdef CONFIG_PM_SLEEP.
