Merge "qcom: subsys-pil-tz: Add property for setting clock frequencies"

- active-clock-names: Names of the clocks that need to be turned on for the

		      subsystem to run. Turned off when the subsystem is shutdown.

- clock-names:	      Names of all the clocks that are accessed by the subsystem.

- qcom,<clock-name>-freq: Frequency to be set for that clock in Hz. If the property

			  isn't added for a clock, then the default clock frequency

			  would be set to 19200000 Hz.

- qcom,msm-bus,name:  Name of the bus client for the subsystem.

- qcom,msm-bus,num-cases: Number of use-cases.

- qcom,msm-bus,num-paths: Number of paths.
