Extend memory probe interface to support an extra paramter nid,
the reserved memory can be added into this node if node exists.

Add a memory section(128M) to node 3(boots with mem=1024m)

	echo 0x40000000,3 > memory/probe

And more we make it friendly, it is possible to add memory to do

	echo 3g > memory/probe
	echo 1024m,3 > memory/probe

It maintains backwards compatibility.

Another format suggested by Dave Hansen:

	echo physical_address=0x40000000 numa_node=3 > memory/probe

it is more explicit to show meaning of the parameters.

I don't like this interface, I think it would be much better to map the 
memory region to the desired node id prior to using probe as an extention 
to debugfs.
