qualcommax: ipq807x: 301w: correct PHY mode for AQR
Interfaces that have AQR-s attached to them are using USXGMII and not just
the default SGMII.
This was fine until SSDK added some sanity checking and now on Qnap 301W it
would fail with:
[ 24.740197] nss-dp
3a001800.dp5 10g-1 (uninitialized): failed to connect to phy device
[ 24.740264] nss-dp: probe of
3a001800.dp5 failed with error -14
So, lets fix 10G AQR ports by declaring the correct PHY mode.
