replace runtime power management primitives in kaweth driver

This patch removes a rare use of the USB power management API which won't be supported after the conversion to the new generic runtime power management framework. Functionality is not altered.

Hi,

please accept this for the next merge window. It will be needed for the adoption of the generic framework for USB.

Regards
Oliver
