Convert kpss-gcc driver Documentation to yaml. Since kpss-gcc expose a
clock add the required '#clock-cells' binding while converting it.

-- compatible:
- Usage: required
- Value type: <string>
- Definition: should be one of the following. The generic compatible
- "qcom,kpss-gcc" should also be included.
- "qcom,kpss-gcc-ipq8064", "qcom,kpss-gcc"
- "qcom,kpss-gcc-apq8064", "qcom,kpss-gcc"
- "qcom,kpss-gcc-msm8974", "qcom,kpss-gcc"
- "qcom,kpss-gcc-msm8960", "qcom,kpss-gcc"
-
-- reg:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: base address and size of the register region
-
-- clocks:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: reference to the pll parents.
-
-- clock-names:
- Usage: required
- Value type: <stringlist>
- Definition: must be "pll8_vote", "pxo".
-
-- clock-output-names:
- Usage: required
- Value type: <string>
- Definition: Name of the output clock. Typically acpu_l2_aux indicating
- an L2 cache auxiliary clock.
-
-Example:
-
- l2cc: clock-controller@2011000 {

- reg = <0x2011000 0x1000>;
- clocks = <&gcc PLL8_VOTE>, <&gcc PXO_SRC>;
- clock-names = "pll8_vote", "pxo";
- clock-output-names = "acpu_l2_aux";
- };
