Hmm, the start/stop latencies are clearly properties of the hardware,
but the save/restore latencies seem to be a function of the driver.
e.g., some drivers may keep a shadow copy of their registers in memory
so the save time is minimized.

I don't have too strong of an opinion on this, but probably the drivers
should just add their own values to the start/stop latencies to add the
linux specific overhead.
