Include it from <linux/hwmon-sysfs.h>. This should cover almost all
drivers needing it. The remaining drivers (if there are any) should
include it directly. Almost all drivers registering the hwmon device
with [devm_]hwmon_device_register_with_info() do not need the include,
but (almost) all drivers registering with an older API will need it.
Those drivers will also include <linux/hwmon-sysfs.h>.
