    This patch implements uevent suppress in kobject and removes it
    from struct device, based on the following ideas:
    
    1,Uevent sending should be one attribute of kobject, so suppressing it
    in kobject layer is more natural than in device layer. By this way,
    we can do it for other objects embedded with kobject.
    
    2,It may save several bytes for each instance of struct device.(On my
    omap3(32bit ARM) based box, can save 8bytes per device object)
    
    This patch also introduces dev_set|get_uevent_suppress() helpers to
    set and query uevent_suppress attribute in case to help kobject
    as private part of struct device in future.
