driver-core: make devt_attr and uevent_attr static

Browse source 
devt_attr and uevent_attr are either allocated dynamically with or
embedded in device and class_device as they needed their owner field
set to the module implementing the driver.  Now that sysfs implements
immediate disconnect and owner field removed from struct attribute,
there is no reason to do this.  Remove these attributes from
[class_]device and use static attribute structures instead.
