[PATCH v2 2/2] arm64: dts: qcom: kaanapali: fix traceNoC probe issue

The AMBA bus attempts to read the CID/PID of a device before invoking
its probe function if the arm,primecell-periphid property is absent.
This causes a deferred probe issue for the TraceNoC device, as the
CID/PID cannot be read from the periphid register.
Add the arm,primecell-periphid property to bypass the AMBA bus
check and resolve the probe issue.
