[PATCH v9 1/4] ASoc: PCM6240: Create PCM6240 Family driver code

[Shenghao Ding]

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@xxxxxx>

---
v9:
 - fixed wrong return value in order to report errors to users in
   pcmdev_put_volsw
 - fixed indentation in pcmdevice_process_block， each case was
   encapsulated into a function
 - Gain kcontrols end with Volume
 - rename the Gain kcontrol
 - Add upper_dev_name in pcmdevice_priv for kcontrol complying with alsa
   naming
v8:
 - use some reasonable format of changelog.
