e1000: unify WoL capability detection code
WoL is constantly giving problems and needed a rewrite. Consolidates all WoL capabilities into a single function, and disables WoL for all other ports on the device except for port A. Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com>
