Subject: [PATCH 6.8 156/715] arm64: dts: qcom: sm6115: declare VLS CLAMP register for USB3 PHY

[ Upstream commit 95d739ed962c9aaa17d77b739606dbdf31879f6e ]

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.
