[PATCH v5 1/5] dt-bindings: arm: coresight-tnoc: Drop arm,primecell to bind on platform bus

[Jie Gan]

The TNOC compatible previously required the two-string AMBA form
"qcom,coresight-tnoc", "arm,primecell", which forces the device onto the
AMBA bus.

Change the compatible to a single "qcom,coresight-tnoc" string with no
"arm,primecell" entry, so the device is created on the platform bus and
bound by the platform driver through its compatible string.

Drop the custom select block as well. It was only needed to avoid
matching the "arm,primecell" string on unrelated nodes; with the single
"qcom,coresight-tnoc" compatible the schema's auto-generated select
already matches the right nodes.

Update the example node to use the standalone compatible form.
