dt-bindings: clock: Add MSM8917 global clock controller

Add a device tree binding to describe clocks, resets and power domains
provided by the global clock controller on MSM8917 SoCs and the very
similar QM215 SoCs.

Add the new compatibles to qcom,gcc-msm8909.yaml. There is
no need to create another YAML file because the bindings are identical
(MSM8917 GCC requires the same parent clocks as the MSM8909 GCC).
