ASoC: rt5677: Support DSP function for VAD application
The ALC5677 has a programmable DSP, and there is a SPI that is dadicated for DSP
firmware loading. Therefore, the patch includes a SPI driver for writing the DSP
firmware. The VAD(Voice Activaty Detection) has be implemented and use the DSP to
recognize the key phase.
