The new phy-j721e-wiz driver causes a link failure without CONFIG_OF: drivers/phy/ti/phy-j721e-wiz.o: In function `wiz_remove': phy-j721e-wiz.c:(.text+0x40): undefined reference to `of_platform_device_destroy' Add a dummy version of of_platform_device_destroy to avoid having to add Kconfig dependencies for the driver. As there are a few other functions without dummy implementations, add those as well for completeness.
