[PATCH V4] powerpc/prom: Export device tree physical address via proc

> V4: Fixed misspelling

Any particular reason you fixed only one of the two
mispelings I pointed out?  (device tree is two words,
not one).

You could use one property instead of two; use addr+len
like every other property does.

You also should use a better name for the property; is this
the previous kernel's device tree?  Just "device-tree" makes
no sense, it is not pointing to "the" device tree for sure!
