[RFC patch 2/5] ASoC: tlv320aic31xx: Add support for pll_r coefficient

When the clock used by the codec is BCLK, the operation parameters need to be calculated from input sample rate and format. Low frequency rates required different r multipliers, in order to achieve a higher PLL output frequency.
