commit 7f654157f0aefba04cd7f6297351c87b76b47b89 upstream.

When CONFIG_PM_SLEEP is disabled, the compiler warns about unused
functions:

drivers/net/phy/phy_device.c:273:12: error: unused function 'mdio_bus_phy_suspend' [-Werror,-Wunused-function]
static int mdio_bus_phy_suspend(struct device *dev)
drivers/net/phy/phy_device.c:293:12: error: unused function 'mdio_bus_phy_resume' [-Werror,-Wunused-function]
static int mdio_bus_phy_resume(struct device *dev)

The logic is intentional, so just mark these two as __maybe_unused
and remove the incorrect #ifdef.

Fixes: 4c0d2e96ba05 ("net: phy: consider that suspend2ram may cut off PHY power")
