coresight: OS unlock for non-krait CPUs using memory mapped access
On CPUs which implement OS lock mechanism, the ETM driver needs to unlock
the OS lock in order to configure ETM registers. Implement OS unlock on
CPUs using a memory mapped access instead of cp14. This is necessary on
CPUs which implement OS lock mechanism and provide only memory mapped
accesss to ETM registers.
