In case of missing CPU phandle, the affinity is set default to
CPU0 which is not a correct assumption. Fix this in coresight
platform to set affinity to invalid and abort the probe in drivers.
Also update the dt-bindings accordingly.

v3:
 * Addressed review comments from Suzuki and updated
   acpi_coresight_get_cpu.
 * Removed patch 2 which had invalid check for online
   cpus.

v2:
 * Addressed review comments from Suzuki and Mathieu.
 * Allows the probe of etm and cpu-debug to abort earlier
   in case of unavailability of respective cpus.
