e1000e: disable broken PHY wakeup for ICH10 LOMs, use MAC wakeup instead

commit 4def99bbfd46e05c5e03b5b282cb4ee30e27ff19 upstream.

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).
