acer-wmi: add ACER_WMID_v2 interface flag to represent new notebooks
There have new acer notebooks' BIOS provide new WMID_GUID3 and
ACERWMID_EVENT_GUID methods.
Some of machines still keep the old WMID_GUID1 method but more and
more machines were already removed old wmi methods from DSDT.
So, this patch add a new ACER_WMID_v2 interface flag to represent
new acer notebooks, the following is definition:
+ ACER_WMID:
It means this machine only provides WMID_GUID1/2 methods.
+ ACER_WMID_v2:
It means this machine provide new WMID_GUID3 and WMID_EVENT_GUID
methods.
Some ACER_WMID_v2 machines also provide old WMID_GUID1/2 methods,
but we still query/set communication device's state by new
WMID_GUID3 method.
Tested on Acer Travelmate 8572
Tested on Acer Aspire 4739Z
