arm64: dts: qcom: msm8916: Add the clocks for the APCS mux/divider

Specify the clocks that feed the APCS mux/divider instead of using
default hardcoded values in the source code.

The driver still supports the previous bindings; however with this
update it we allow the msm8916 to access the parent clock names
required by the driver operation using the device tree node.
