ASoC: wm8962: mark cache_dirty flag after software reset in pm_resume

By doing software reset of wm8962 in pm_resume, all registers which
have already been set will be reset to default value without regmap
interface be involved, thus driver need to mark cache_dirty flag,
to let regcache can be updated by regcache_sync().
