ARM: dts: qcom: add and fix clock configuration for kpss-gcc nodes

Add missing clock configuration by adding clocks, clock-names
and #clock-cells bindings for each kpss-acc-v1 clock-controller
node for apq8064 and msm8960 to reflect Documentation schema.
Add missing #clock-cells binding and remove useless clock-output-names for
ipq806x dtsi.
