[PATCH v2 6/6] arm64: dts: qcom: sm6115: declare VLS CLAMP register for USB3 PHY

The USB3 PHY on the SM6115 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: 9dd5f6dba729 ("arm64: dts: qcom: sm6115: Add USB SS qmp phy node")
