skge: adapt skge to use reworked PCI PM
Adapt the skge driver to the reworked PCI PM
* Use device_set_wakeup_enable() and friends as needed
* Remove an open-coded reference to the standard PCI PM registers
* Use pci_prepare_to_sleep() and pci_back_from_sleep() in the
->suspend() and ->resume() callbacks
* Use the observation that it is sufficient to call pci_enable_wake()
once, unless it fails
Tested on Asus L5D (Yukon-Lite rev 7).
