ACPI: delete OSI(Linux) DMI dmesg spam

In 2.6.28 a6e0887f21bbab337ee32d9c0a84d7c0b6e9141b removed this code
because the linux-acpi community no longer needs the feedback
that these console messages solicit.

here in .stable, we apply a simpler version of that patch,
but for the exact same reasons.
