drm/rockchip: vop2: Use regcache_sync() to fix suspend/resume
commit b63a553e8f5aa6574eeb535a551817a93c426d8c upstream. afa965a45e01 ("drm/rockchip: vop2: fix suspend/resume") uses regmap_reinit_cache() to fix the suspend/resume issue with the VOP2 driver. During discussion it came up that we should rather use regcache_sync() instead. As the original patch is already applied fix this up in this follow-up patch.
