[PATCH 2/6] dt-bindings: phy: qcom,msm8998-qmp-usb3-phy: add TCSR registers

[Dmitry Baryshkov]

The QMP USB PHYs on msm8998, qcm2290 and some other platforms don't have
the PCS_MISC_CLAMP_ENABLE register. Instead they need to toggle the
register in the TCSR space. Declare the registers accessible through the
TCSR space.
