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.

The header file is needed because struct gpio_chip is
placed in struct rt5677_priv.

Some boards have this pin statically tied and do not require any configuration,
some other boards allow to enable chip using GPIO.
Add an option that tells which GPIO is used to power the audio codec.

There are two pins can be used for rt5677's DMIC2 clock. This patch
add the select options for it.

The implementation of rt5677_pll_calc() has the same logic of rl6231_pll_calc().
The only difference is the lower boundary checking for freq_in.
This patch calls rl6231_pll_calc() instead of open-coded.
The k_bp of struct rt5677_pll_code is always false, thus also remove the
code to check pll_code.k_bp.
