drm/rockchip: vop2: Use regcache_sync() to fix suspend/resume

Browse source

commit b63a553e8f upstream.

afa965a45e ("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.
