This patch is to address PEM initialization issue
which causes network issues.
It is necessary to search for _HID:PNP0A08 while requesting
PEM resources via ACPI instead of "THRX0002".
Since this is fixing new code, there should be no chance to break
previously working systems.
Bjorn: If possible, this should be merged for v4.10
