[ Upstream commit fc835b2311d4deb85d776c1d73562338462aa7ac ]
The USB3 PHY on the MSM8998 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: 026dad8f5873 ("arm64: dts: qcom: msm8998: Add USB-related nodes")
