Brandon Bergren 26869ad14c [PowerPC] Allow traversal of oversize OF properties. 
In standards such as LoPAPR, property names in excess of the usual 31
characters exist.

This breaks property traversal.

While in IEEE 1275-1994, nextprop is defined explicitly to work with a
32-byte region of memory, using a larger buffer should be fine. There is
actually no way to pass a buffer length to the nextprop call in the OF
client interface, so SLOF actually just blindly overflows the buffer.

So we have to defensively make the buffer larger, to avoid memory
corruption when reading out long properties on live OF systems.

Note also that on real-mode OF, things are pretty tight because we are
allocating against a static bounce buffer in low memory, so we can't just
use a huge buffer to work around this without it being wasteful of our
limited amount of 32-bit physical memory.

This allows a patched ofwdump to operate properly on SLOF (i.e. pseries)
systems, as well as any other PowerPC systems with overlength properties.
