regmap: Add basic tracepoints Trace single register reads and writes, plus start/stop tracepoints for the actual I/O to see where we're spending time. This makes it easy to have always on logging without overwhelming the logs and also lets us take advantage of all the context and time information that the trace subsystem collects for us. We don't currently trace register values for bulk operations as this would add complexity and overhead parsing the cooked data that's being worked with.
