Sai Prakash Ranjan 996cdfaf53 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.
