Subject: [PATCH v2 2/2] arm64: dts: qcom: hamoa: enable ETR and CTCU
devices
Embedded Trace Router(ETR) is working as a DDR memory sink to collect
tracing data from source device.
The CTCU serves as the control unit for the ETR device, managing its
behavior to determine how trace data is collected.
