Compiling yaboot with DEBUG=1 generates lot of warnings.

This patch fixes most of those.

Left couple of warnings as they would require close scrutiny.

I don't think that's a good change. block_buffer contains binary data
and may contain values outside 0-127 scope, that's why it should be
explicitly marked as signed or unsigned. I guess unsigned is better in
this case.
