[PATCH 5/6] arm64: dts: qcom: qcm2290: declare VLS CLAMP register for USB3 PHY

The USB3 PHY on the QCM2290 platform doesn't have built-in
PCS_MISC_CLAMP_ENABLE register. Instead clamping is handled separately
via the register in the TCSR space. Declare corresponding register.

Fixes: 0c55f6229bc3 ("arm64: dts: qcom: qcm2290: Add USB3 PHY")
