memory: move hotplug memory notifier priority to same file for easy sorting

Browse Source 
The priority of hotplug memory callback is defined in a different file. 
And there are some callers using numbers directly.  Collect them together
into include/linux/memory.h for easy reading.  This allows us to sort
their priorities more intuitively without additional comments.
