[PATCH v3 02/12] ASoC: sun4i-i2s: Add clkdiv offsets to quirks

[codekipper at gmail.com]

From: Marcus Cooper <codekipper at gmail.com>

The BCLKDIV and MCLKDIV found on newer SoCs start from an offset of 1.
Add the functionality to adjust the division values according to the
needs to the device being used.
