Subject: [PATCH] of: add dummy of_platform_device_destroy

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 this function to avoid having to add Kconfig
dependencies for the driver.

Fixes: 42440de5438a ("phy: ti: j721e-wiz: Add support for WIZ module present in TI J721E SoC")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
