sky2: remove check for PCI wakeup setting from BIOS

Browse source 
The driver checks status of PCI power management to mark
default setting of Wake On Lan. On some systems this works, but often
it reports a that WOL is disabled when it isn't.

This patch gets rid of that check and just reports the wake on
lan status based on the hardware capablity.
