Lars-Peter Clausen e409dfbfcc ASoC: dapm: Add a few supply widget sanity checks 
Supply widgets are somewhat special and not all kinds of paths to or from
supply widgets make sense. This patch adds a few sanity checks that errors
out during the path instantiation for those invalid paths. This will prevent
drivers to depend on weird behavior resulting from such paths as well as
will allow the DAPM algorithms to assume that they never see such paths.

This patch adds checks for the following three invalid types of paths:
	* A path with a non-supply widget as a source connected to a supply
	  widget as a sink. Such a path has no effect on either of the two
	  connected widgets.
	* Paths with a connected() callback that have a non-supply widget as the
	  source. The DAPM algorithm only uses the conneceted() callback for
	  supply widget power checks. And since it prevents caching of the DAPM
	  state there is no intention to make it more generic as it has
	  negative performance implications.
	* Paths which connect a supply to a mixer or mux via a control. Controls
	  are only meant to affect the routing of audio data.
