ASoC: da7213: Add DAI DAPM event to control DAI clocks
Currently, when Codec is I2S master DAI clocks are continuously generated even if all audio streams have stopped. To improve efficiency, control of the DAI clocks for master mode have been moved to a DAPM widget event so they're only enabled as required.
