[ALSA] ASoC: Add support for BCLK based on (Rate * Chn * Word Size)
This patch adds support for the DAI BCLK to be generated by multiplying Rate * Channels * Word Size (RCW). This now gives 3 options for BCLK clocking and synchronisation :- 1. BCLK = Rate * x 2. BCLK = MCLK / x 3. BCLK = Rate * Chn * Word Size. (New) Changes:- o Add support for RCW generation of BCLK o Update Documentation to include RCW. o Update DAI documentation for label = value DAI modes. o Add RCW support to wm8731, wm8750 and pxa2xx-i2s drivers.
