Subject: [PATCH] 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.
