[RESEND PATCH v2 0/2] ASoC: atmel-pdmic: add driver for Atmel PDMIC

[Songjun Wu]

The Pulse Density Modulation Inteface Controller driver
includes two parts.
1) Driver code to implement the PDMIC function.
2) Device tree binding documentation, it describes how to add
   the PDMIC in device tree.

Changes in v2:
- Remove the function 'atmel_pdmic_codec_get_remap', since the regmap
  is initialized in the core.
- Replace 'if' with 'switch' in function 'atmel_pdmic_codec_dai_hw_params'.
- Fix the coding style issue in function 'atmel_pdmic_dt_init',
  'atmel_pdmic_interrupt','pdmic_put_mic_volsw', 'atmel_pdmic_codec_probe',
  'pdmic_get_mic_volsw' and 'atmel_pdmic_codec_dai_hw_params'.
