[PATCH v5 1/3] clk: qcom: gcc-msm8960: create tsens device if there are no child nodes

[Dmitry Baryshkov <dmitry.baryshkov@linaro.org>]

Currently gcc-msm8960 driver manually creates tsens platform device
manually. It would be better to follow IPQ8064 approach, where tsens
device is defined as gcc's child device in the device tree. If nothing
else, it removes gcc's dependency on QFPROM, thus allowing clock
controller to be probed earlier.

Don't create it in case there are available child nodes (tsens) inside
the gcc's device tree node.
