    ramips: Fix wmac dts definition for TP-Link TL-MR6400 v4 and v5
    
    This code assumed that the mt7628an_tplink_8m.dtsi file defines
    mediatek,mtd-eeprom for the wmac and sets status to okay.
    
    The mediatek,mtd-eeprom definition was removed in commit e93f41adee3e
    ("ramips: convert MT7628 EEPROM to NVMEM format") but the dts for these
    two devices was not adapted to include the eeprom position on its own.
    
    The status = "okay" property was removed in 0a1d15642fa6 ("ramips:
    mt7628: use nvmem-layout"), but the property was not added to these dts
    files.
    
    Without this change wifi does not work for these devices.

    Fixes: 0a1d15642fa6 ("ramips: mt7628: use nvmem-layout")
