[PATCH 2/2] clk: qcom: gcc bindings: Update to add child node support.

[Srinivas Kandagatla <srinivas.kandagatla@linaro.org>]

This patch adds note in the bindings about the optional child nodes
which are currently possible with SOCs like MSM8960, APQ8064.
These child device nodes are typically for drivers like thermal sensor
which fall under the memory-map of gcc.
