dt-bindings: clock: qcom,hfpll: Convert to YAML

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
