PCI: sysfs: Define device attributes with DEVICE_ATTR*()

Device attributes should be defined using DEVICE_ATTR*(_name, _mode, _show,
_store).  Convert them all from __ATTR*() to DEVICE_ATTR*(), e.g.,

  - struct device_attribute dev_attr_##_name = __ATTR(_name, _mode, _show,
                                                      _store)
  + static DEVICE_ATTR(foo, S_IWUSR | S_IRUGO, show_foo, store_foo)
