net: phy: mdio-bcm-unimac: mark PM functions as __maybe_unused

The newly added runtime-pm support causes a harmless warning
when CONFIG_PM is disabled:

drivers/net/phy/mdio-bcm-unimac.c:330:12: error: 'unimac_mdio_resume' defined but not used [-Werror=unused-function]
 static int unimac_mdio_resume(struct device *d)
drivers/net/phy/mdio-bcm-unimac.c:321:12: error: 'unimac_mdio_suspend' defined but not used [-Werror=unused-function]
 static int unimac_mdio_suspend(struct device *d)

Marking the functions as __maybe_unused is the easiest workaround
and avoids adding #ifdef checks.
