    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
