ARM: dts: msm: Add support for cpu clocks for msm8937

Qualcomm Technology Inc MSM8939 CPU clock tree

clock-cpu-8939 is a device that represents the MSM8939 or MSM8952 CPU

subsystem clock tree. It lists the various power supplies that need to be

scaled when the clocks are scaled and also other HW specific parameters like

fmax tables, avs settings table, etc.

Required properties:

- compatible:		Must be one of "qcom,clock-cpu-8939" or

			"qcom,cpu-clock-8952"

- reg:			Pairs of physical base addresses and region sizes of

			memory mapped registers.

- reg-names:		Names of the bases for the above registers. Expected

			bases are:

			"apcs-c0-rcg-base", "apcs-c1-rcg-base",

			"apcs-cci-rcg-base", "efuse", "efuse1", "efuse2"

- vdd-c0-supply:	The regulator powering the little cluster

- vdd-c1-supply:	The regulator powering the big cluster

- vdd-cci-supply:	The regulator powering the CCI cluster

- qcom,speedX-bin-vY-ZZZ:

			A table of CPU frequency (Hz) to voltage (corner)

			mapping that represents the max frequency possible

			for each supported voltage level for a CPU. 'X' is

			the speed bin into which the device falls into - a

			bin will have unique frequency-voltage relationships.

			'Y' is the characterization version, implying that

			characterization (deciding what speed bin a device

			falls into) methods and/or encoding may change. The

			values 'X' and 'Y' are read from efuse registers, and

			the right table is picked from multiple possible tables.

			'ZZZ' can be c1, c0 or cci depending on whether the table

			is for the big cluster, little cluster or cci.

Optional properties:

- qcom,cpu-pcnoc-vote:  Boolean to indicate cpu clocks would need to keep

			active pcnoc vote.
