    chromeec: Add ACPI device for PD MCU and handle related EC host event
    
    Add ACPI device for PD MCU, if present. Call Notify routine when the
    corresponding EC host event is received.
    
    BUG=chrome-os-partner:31361
    TEST=Manual on Samus. Enable EC_ENABLE_PD_MCU_DEVICE, unmask PD MCU host
    event, and verify ACPI Notify routine is called when host event is sent
    from EC.
    BRANCH=None.
