Convert the .txt documentation to .yaml with some adjustments.
* APQ8064/IPQ8064/MSM8960 compatibles are dropped since their HFPLLs are
a part of GCC so there is no need for a separate compat entry.
* Change the MSM8974 compatible to follow the updated naming schema.
Theis compatible is not used upstream yet.
* Add qcs404-hfpll. QCS404 currently uses qcom,hfpll. Mark that as
deprecated since every SoC appears to need different driver data so
"qcom,hfpll" makes no sense to keep

-- compatible:
- Usage: required
- Value type: <string>:
- shall contain only one of the following. The generic
- compatible "qcom,hfpll" should be also included.
-
- "qcom,hfpll-ipq8064", "qcom,hfpll"
- "qcom,hfpll-apq8064", "qcom,hfpll"
- "qcom,hfpll-msm8974", "qcom,hfpll"

-
-- reg:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: address and size of HPLL registers. An optional second
- element specifies the address and size of the alias
- register region.
-
-- clocks:
- Usage: required
- Value type: <prop-encoded-array>
- Definition: reference to the xo clock.
-
-- clock-names:
- Usage: required
- Value type: <stringlist>
- Definition: must be "xo".
-
-- clock-output-names:
- Usage: required
- Value type: <string>
- Definition: Name of the PLL. Typically hfpllX where X is a CPU number
- starting at 0. Otherwise hfpll_Y where Y is more specific
- such as "l2".
-
-Example:
-
-1) An HFPLL for the L2 cache.
-
- clock-controller@f9016000 {
- compatible = "qcom,hfpll-ipq8064", "qcom,hfpll";
- reg = <0xf9016000 0x30>;
- clocks = <&xo_board>;
- clock-names = "xo";
- clock-output-names = "hfpll_l2";
- };
-
-2) An HFPLL for CPU0. This HFPLL has the alias register region.
-
- clock-controller@f908a000 {
- compatible = "qcom,hfpll-ipq8064", "qcom,hfpll";
- reg = <0xf908a000 0x30>, <0xf900a000 0x30>;
- clocks = <&xo_board>;
- clock-names = "xo";
- clock-output-names = "hfpll0";
- };
