ENGR00170627 imx-cs42888: overwrite codec_name if passed as platform data

* Overwrite codec_name if passed as platform data
* Add codec_name in mxc_audio_platform_data
* Codec name follows the naming convention
  <codec>.<i2c-channel>-<codec i2c address> i.e. cs42888.0-0048
* For IMX6Q-ARD this name convention doesn't follow previous settings for
  imx6q platforms codec is on different i2c channel and can't be resolved
  by CONFIG macros on imx_3stack_dai data structure; So we overwrite in
  probe function by getting the correct value from plat_data->codec_name.
