phy: qcom: qmp-usbc: handle CLAMP register in a correct way

Browse source

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. Make the new phy-qcom-qmp-usbc driver
correctly handle the clamp register.
