Subject: [PATCH 1/3] ASoC: da7219: Update DAI clock binding info to cover
 WCLK/BCLK

With the need to expose WCLK and BCLK as separate clocks, the
'clock-cells' and 'clock-output-names' descriptions need to be
updated as now the codec is providing 2 clocks. The example is
also updated accordingly.
