qualcommax: ipq807x: 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

Since this is not Qnap 301W specific lets fix it subtarget wide by
declaring the correct PHY mode for 10G AQR-s.
