ASoC: Add MICFIL SoC Digital Audio Interface driver.
Add Digital Audio Interface driver that convers PDM bitstream to PCM
format.
Features:
- Fixed filtering characteristics for audio application.
- Full or partial set of channels operation with individual enable control.
- Programmable PDM clock generator.
- Programmable decimation rate.
- 16-bit signed output result.
- Overall stopband attenuation more than 80dB.
- Overall passband ripple less than 0.2dB.
