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.

tnoc.c registers both an AMBA driver and a platform driver. Shouldn't it be registered as a platform device instead?
