[PATCH] ppc64: increase TREEWORDS value in ppc64

[Neil Horman]

hey-
     Got a segfault recently on ppc64 kexec with a system with 256Gb of ram.
Tracked it back to running over the end of the device tree buffer that we have
allocated.  I can't find any docs on how big the device tree can legally be, so
for now I figure just upping its size is sufficient.  Confirmed that this fixed
the segfault.
