power: support _noirq actions on device types and classes

The new-style dev_pm_ops provide callbacks for both IRQs enabled
and disabled. However, the _noirq variants were only called for
buses registered with a device, not for classes and types.

In order to properly use dev_pm_ops in class pcmcia_socket_class,
support _noirq actions also on classes and types.
