Let's ensure our PCI device is awaken on every sysfs call. Let's increase the runtime_pm protection and start moving that to the outer bounds. For now, for the files with small number of attr functions, let's only call the runtime pm functions directly. For the hw_engines entries with many files, let's add the sysfs_ops wrapper.
