clk: qcom: create virtual child device for TSENS
8960 family of devices have TSENS as part of GCC in hardware. Hence DT would represent a GCC node with GCC properties as well as TSENS. Create a virtual platform child device here for TSENS so the driver can probe it and use the parent (GCC) to extract DT properties.
