ASoC: nau8822: add MCLK support

Browse source

This change adds MCLK clock handling directly within driver.
When used in combination with simple-audio-card, and mclk-fs is set,
simple-audio-card will change MCLK frequency before configuring PLL.
In some cases, however, MCLK reference clock should be static (see [1]),
which means it needs to be moved away from simple-audio-card.
