arm64: dts: qcom: qcm2290: declare VLS CLAMP register for USB3 PHY
[ Upstream commit acb94d67f5a23dbb2e0021b6c30609ed05d7d6a5 ]
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.
