coresight: set invalid default cpu id
Current code sets default CPU id as of CPU0. This causes a failure in
case where device tree declares a CoreSight node that is associated with
a CPU that's not available on that target. This causes complete failure of
the system.
Set default CPU id to -1 to avoid this problem.
