Introduce .is_enabled() and .enable() callbacks to handle PLL state transitions. With the .enable() callback, the PLL will be turned ON only when the PLL consumer device is enabled; otherwise, it will remain off. Define new macros for PLL standby and monitor registers to facilitate this process.

These clocks supply the coresight tracing modules, PTM, TPIU, ETB and replicator. Without these clocks, coresight tracing can not be operated. While this does change the ABI, it does so by extending the existing clock-output-names, therefore if old software is used with new DT, the coresight tracing parts will likely fail to probe, otherwise if new software is used with an old DT, there is no impact.

These clocks supply the coresight tracing modules, PTM, TPIU, ETB and replicator. Without these clocks, coresight tracing can not be operated. While this does change the ABI, it does so by extending the existing clock-output-names, therefore if old software is used with new DT, the coresight tracing parts will likely fail to probe, otherwise if new software is used with an old DT, there is no impact.
