ASoC: core: Add set_fmt_new callback that directly specifies provider
The original 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. Now everything is
componentised it simplifies things if each side of the link is
just told if it is provider or consumer of the clocks. To start
this migration add a new callback that can be used to receive a
direct specification of clocking. As there are more CODEC drivers
than platform drivers, we make the new flags identical to the old
CODEC flags meaning CODEC drivers will not require an update.
