According to the kernel 4.4 sources from NHSS.QSDK.9.0.2 and according
to hardware docs, the PHY registers layout used for IPQ8074 USB3 PHY is
incorrect. This platform uses offset 0x174 for the PCS_STATUS register,
0xd8 for PCS_AUTONOMOUS_MODE_CTRL, etc.

Correct the PHY registers layout.

Fixes: 94a407cc17a4 ("phy: qcom-qmp: create copies of QMP PHY driver")
Fixes: 507156f5a99f ("phy: qcom-qmp: Add USB QMP PHY support for IPQ8074")

Reviewed the docs, changes looks good to me.
