Provide some basic trace facilities to the regulator API. We generate events on regulator enable, disable and voltage setting over the actual hardware operations (which are assumed to be the expensive ones which require interaction with the actual device). This is intended to facilitate debug of the performance and behaviour with consumers allowing unified traces to be generated including the regulator operations within the context of the other components of the system. For enable we log the explicit delay for the voltage ramp separately to the interaction with the hardware to highlight the time consumed in I/O. We should add a similar delay for voltage changes, though there the relatively small magnitude of the changes in the context of the I/O costs makes it much less critical for most regulators. Only hardware interactions are currently traced as the primary focus is on the performance and synchronisation of actual hardware interactions. Additional tracepoints for debugging of the logical operations can be added later if required.
