Move schema for qcom,sdm845-mdss from dpu-sdm845.yaml to mdss.yaml so
that the dpu file describes only the DPU schema.

I still don't think this is better approach than what I proposed - to
have common MDSS schema used by several device-specific schemas (e.g.
sdm845-mdss.yaml or existing dpu-sdm845.yaml).

It's not only difficulty to review the patch but also to understand the
binding which grows huge.

This was not allowed for qcom,mdss. Same with iommus.
