The cw1200 driver implements suspend and resume callbacks and assigns them
to the suspend and resume fields of the device_driver struct. These
callbacks are never actually called by anything though.
Modify the driver to properly use dev_pm_ops so that the suspend function
is actually executed upon suspend and drop the empty resume function.
