[PATCH] powerpc: make iSeries flattened device tree dynamic

First we capture all the strings from dt.c statically by noting that gcc
puts them in a special section of their own.  Idea from Michael Ellerman.

Then we move the flattened device tree to klimit.

Still to come, making the values blob grow as needed.
