phy: qcom-qmp-usb: correct registers layout for IPQ8074 USB3 PHY
[ Upstream commit 922adfd59efd337059f8445a8d8968552b06ed4e ]
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.
