Bryan O'Donoghue 0c0f65c6dd dt-bindings: msm: dsi-controller-main: Add compatible strings for every current SoC
Currently we do not differentiate between the various users of the
qcom,mdss-dsi-ctrl. The driver is flexible enough to operate from one
compatible string but, the hardware does have some significant differences
in the number of clocks.

To facilitate documenting the clocks add the following compatible strings

- qcom,apq8064-dsi-ctrl
- qcom,msm8916-dsi-ctrl
- qcom,msm8953-dsi-ctrl
- qcom,msm8974-dsi-ctrl
- qcom,msm8996-dsi-ctrl
- qcom,msm8998-dsi-ctrl
- qcom,sc7180-dsi-ctrl
- qcom,sc7280-dsi-ctrl
- qcom,sdm660-dsi-ctrl
- qcom,sdm845-dsi-ctrl
- qcom,sm8150-dsi-ctrl
- qcom,sm8250-dsi-ctrl
- qcom,sm8350-dsi-ctrl
- qcom,sm8450-dsi-ctrl
- qcom,sm8550-dsi-ctrl
- qcom,qcm2290-dsi-ctrl

Deprecate qcom,dsi-ctrl-6g-qcm2290 in favour of the desired format while we
do so.

Several MDSS yaml files exist which document the dsi sub-node.
For each existing SoC MDSS yaml, provide the right dsi compat string.
