Subject: [PATCH net] of: mdio: mark stub of_mdiobus_child_is_phy as inline

The of_mdiobus_child_is_phy function was recently exported, with a stub
fallback added to simply return false as a static function. The inline
specifier was left out, leading to build time errors:

In file included from linux/include/linux/fs_enet_pd.h:21,
                 from linux/arch/powerpc/sysdev/fsl_soc.c:26:
linux/include/linux/of_mdio.h:58:13: error: ‘of_mdiobus_child_is_phy’ defined but not used [-Werror=unused-function]
   58 | static bool of_mdiobus_child_is_phy(struct device_node *child)
      |             ^~~~~~~~~~

This commit simply adds the missing inline keyboard.
