    platform/x86: x86-android-tablets: Add Advantech MICA-071 extra button
    
    [ Upstream commit b03ae77e7e057f4b3b858f10c840557e71448a91 ]
    
    The Advantech MICA-071 is a standard Windows tablet, but it has an extra
    "quick launch" button which is not described in the ACPI tables in anyway.
    
    Use the x86-android-tablets infra to create a gpio-button device for this.
