coresight: Do not default to CPU0 for missing CPU phandle Coresight platform support assumes that a missing "cpu" phandle defaults to CPU0. This could be problematic and unnecessarily binds components to CPU0, where they may not be. In coresight etm and cpu-debug drivers, abort the probe for such cases.
