drivers/intel/wifi: Use newly added pci_dev_is_wake_source
This change uses the newly added `pci_dev_is_wake_source()` helper function to determine and log WiFi wake source instead of assuming a hard-coded register value to check. This is done in preparation to merge the generic WiFi and Intel WiFi drivers in coreboot in follow-up changes.
