[PATCH] ASoC: wm8974: set cache type for regmap

From: Mans Rullgard
Date: Fri Dec 11 2015 - 06:27:31 EST

Attempting to use this codec driver triggers a BUG() in regcache_sync()
since no cache type is set. The register map of this device is fairly
small and has few holes so a flat cache is suitable.
