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.
