ASoC: wm8974: set cache type for regmap

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

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.
