[PATCH stable 5.16+ 3/3] net: dsa: realtek: make interface drivers depend on OF

[Alvin Šipraga]

From: Alvin Šipraga <alsi@xxxxxxxxxxxxxxx>

[ Upstream commit 109d899452ba17996eccec7ae8249fb1f8900a16 ]

The kernel test robot reported build warnings with a randconfig that
built realtek-{smi,mdio} without CONFIG_OF set. Since both interface
drivers are using OF and will not probe without, add the corresponding
dependency to Kconfig.
