Enable wiphy device to suspend/resume asynchronously. This can 
improve
system suspend/resume speed.

How will that impact the timing with respect to the suspend call
coming from the bus?
I think that a few drivers rely on the suspend call of the wiphy
device happening before the suspend call to the bus device.

Yes, we can't do this for precisely this reason unless we have a way to
somehow keep the dependency between the two - possibly by also marking
the other one as async (although I don't know if the async framework in
general has any FIFO guarantees, which would be required for this.)

I've dropped the patch.
