usb: musb: dma: merge ->start/stop into create/destroy

Browse Source 
The core code creates a controller and immediately after that it calls
the ->start() callback. This one might drop an error but nobody cares.
The same thing happens in the destroy corner: First ->stop() called
followed by destroy callback. So why not merge those two into the same
function since there is no difference.
