    ramips: fix SDXC function for mt76x8 one eth port devices
    
    There are only 5 devices in mt76x8 sub-target selected the MTK SDXC
    driver package. And they are all single ethernet port routers or dev
    boards:
    
    * LinkIt Smart 7688
    * Onion Omega2+
    * RAVPower RP-WD009
    * VoCore VoCore2
    * VoCore VoCore2-Lite
    
    For these devices, they are using the ephy p1 - p4 as the SDXC IO
    pins. Therefore, these GPIO pads must be configured in "digital"
    IO mode.
