ASoC: ak4613: Implement suspend callback
Add the suspend callback to accompany the existing resume operation. With the suspend/resume callbacks the regmap (regcache) state handling can follow the recommended sequence. Based on commit a2ebd58627e9aa48 ("ASoC: ak4642: Implement suspend callback") by Peter Ujfalusi <peter.ujfalusi@ti.com>.
