mfd: arizona: Fix rumtime PM imbalance on error
pm_runtime_get_sync() will increase the rumtime PM counter even it returns an error. Thus a pairing decrement is needed to prevent refcount leak. Fix this by replacing this API with pm_runtime_resume_and_get(), which will not change the runtime PM counter on error.
