Mark Brown bc7ee55633 regmap: Add trace event for successful cache reads
Currently we only trace physical reads, there's no instrumentation if
the read is satisfied from cache.

Mark Brown 3d9ead7c06 regmap: Use int rather than size_t for lengths when logging blocks
x86_64 warns as size_t is not an int.

Mark Brown fb2736bbae 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.
