Specify clock provider directly to CPU DAIs
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>: Currently the set_fmt callback always passes clock provider/consumer with respect to the CODEC. This made sense when the framework was directly broken down into platforms and CODECs. However, as things are now broken down into components which can be connected as either the CPU or CODEC side of a DAI link it simplifies things if each side of the link is just told if it is provider or consumer of the clocks. Making this change allows us to remove one of the last parts of the ASoC core that needs to know if a driver is a CODEC driver, where it flips the clock format specifier if a CODEC driver is used on the CPU side of a DAI link, as well as just being conceptually more consistent with componentisation. The basic idea of this patch chain is to change the set_fmt callback from specifying if the CODEC is provider/consumer into directly specifying if the component is provider/consumer. To do this we add some new defines, and then to preserve bisectability, the migration is done by adding a new callback, converting over all existing CPU side drivers, converting the core, and then finally reverting back to the old callback. Converting the platform drivers makes sense as the existing defines are from the perspective of the CODEC and there are more CODEC drivers than platform drivers. Obviously a fair amount of this patch chain I was only able to build test, so any testing that can be done would be greatly appreciated.
