sky2: Fix WOL regression 

Since dev->power.should_wakeup bit is used by the PCI core to
decide whether the device should wake up the system from sleep
states, set/unset this bit whenever WOL is enabled/disabled using
sky2_set_wol().
    
Remove an open-coded reference to the standard PCI PM registers that
is not used any more.
