When support for 82577/82578 was added[1] in 2.6.31, PHY wakeup was in-
advertently enabled (even though it does not function properly) on ICH10
LOMs.  This patch makes it so that the ICH10 LOMs use MAC wakeup instead
as was done with the initial support for those devices (i.e. 82567LM-3,
82567LF-3 and 82567V-4).
