    ACPI: use LNXCPU, not ACPI_CPU, for Linux-specific processor _HID
    
    ACPI_PROCESSOR_OBJECT_HID is a synthetic _HID that Linux generates
    for "Processor" definitions.  Unlike "Device" definitions, "Processor"
    definitions do not have a _HID in the namespace, so we generate a
    fake _HID.  By convention, all these fake _HIDs begin with "LNX".
    
    This does change the user-visible _HID for "Processor" objects --
    previously, we used "ACPI_CPU" and this changes that to "LNXCPU",
    which starts with "LNX" as do all the other made-up _HIDs.  This
    change is visible in processor filenames and "hid" files under
    /sys/devices/LNXSYSTM:00/.
