coresight: Populate CPU ID into coresight_device

coresight: Populate CPU ID into coresight_device

Add a new flag CORESIGHT_DESC_CPU_BOUND to indicate components that
are CPU bound.  Populate CPU ID into the coresight_device structure;
otherwise, set CPU ID to -1 for non CPU bound devices.

Use the {0} initializer to clear coresight_desc structures to avoid
uninitialized values.
