Yes, originally. But OF is now used more or less as a synonym for "Device Tree", i.e all the kernel functions to parse the Device Tree are prefixed with of_*(). If you don't have CONFIG_SERIAL_OF_PLATFORM=y and your hardware is described by a Device Tree, then your 8250 serial driver will not probe. However, what is a bit weird is to enable both the 8250 driver and the pl011 driver.
