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 Signed-off-by: Luca Weiss <luca@z3ntu.xyz> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Link: https://lore.kernel.org/r/20240218-hfpll-yaml-v2-1-31543e0d6261@z3ntu.xyz Signed-off-by: Bjorn Andersson <andersson@kernel.org>
