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. v4: * Fix return for !CONFIG_ACPI and !CONFIG_OF. 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.
