Subject: [PATCH] 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>.
