mediatek: filogic: PHY LEDs do have an address, gpio-leds don't

Other than GPIO LEDs, PHY LEDs do have an address.

Fix node names such that all gpio-leds do *not* contain an '@' sign and
PHY leds which do have an address also do contain the '@' sign.

This is done to prevent more copy&paste'ry of non-complaint DT
fragments.
