API CHANGE: Remove ma_performance_profile.

Browse Source 
This also removes the `performanceProfile` config option from
`ma_device_config`. Increase the period size if you want to be more
conservative.

Backends that have their own notion of a "latency hint" or the like will
have those options exposed via a backend-specific configuration option.

calculation of the period size as accurate as possible, but sometimes it's just not practical so just use whatever you can.
