[PATCH v4 5/5] arm64: dts: qcom: glymur: use Aggregator TNOC compatible

[Jie Gan <jie.gan@oss.qualcomm.com>]

The traceNoC node is the system-level Aggregator TNOC, so it must own a
valid ATID that tags the whole aggregation path. It is marked compatible
with "qcom,coresight-itnoc", an Interconnect TNOC, which is never
assigned an ATID. As a result the aggregator has no trace ID and cannot
tag the merged trace.

An Interconnect TNOC is a subsystem-level aggregator: it merges trace
from the ATB sources within its subsystem (TPDMs and other ATB masters)
and forwards the combined stream to the system-level Aggregator TNOC. It
carries no ATID of its own, because the Aggregator TNOC downstream in the
path already owns the ATID.

Switch the node to "qcom,coresight-agtnoc" so it is described as the
Aggregator TNOC it is and is assigned a system trace ID. Rename the node
to "tn" and use the "apb_pclk" clock name as required by the Aggregator
TNOC binding.
