PCM6240 driver implements a flexible and configurable setting for register
and filter coefficients, to one, two or even multiple PCM6240 Family Audio
chips.

Signed-off-by: Shenghao Ding <shenghao-ding@ti.com>

Change in v4:
 - All these chips have only a portion of the codec's functionality, such
   as ADC or DAC, and so on, but their audio performance is far superior
   to the codec's, and cost is lower than codec, and much easier to
   program than codec.
 - remove unused data structure.
