hwmon: (pmbus/core) notify on the hwmon device, not the i2c client
pmbus_notify() calls sysfs_notify() and kobject_uevent() on the i2c
client's kobject, but the alarm attributes live on the hwmon class
device registered by pmbus_do_probe(). Notifying the parent i2c device
is a no-op for both poll(POLLPRI) waiters and udev listeners: the named
attribute does not exist on that kobject.
Notify the hwmon device instead, so poll() wakes up and "change"
uevents fire on the inX_alarm/tempX_alarm attributes when SMBALERT#
reports a fault.
