google/panther: Add ACPI code to support wake-on-lan 

There needs to be an ACPI linkage to provide the power resource
needed to wake this device so the kernel will enable the SCI
before going to suspend.

A link is added for both NIC and WLAN, but it is only tested
on the NIC.

This is a forward port from Duncan's beltino patch.

BUG=chrome-os-partner:24657
BRANCH=panther
TEST=build and boot on panther, suspend and wake with etherwake
