On ppc64 the high 32 address bits are clear, so ba's sign extension
cannot be used to branch to the ROM version of exception_return.
Use a relative branch to the relocated version instead.
This fixes relocation linker errors for ppc64.

When cross-compiling ppc64 from ppc (native larger than host),
%llx cell format leads to warnings.
The cell format depends solely on the cell type definition,
not on pointer sizes. Under the present assumption that native
smaller than host bitwidth occurs when cross-compiling a 32-bit
target from 64-bit host, we can reuse the definitions from the
equality path for all bitwidths.

ofmem was fixed at 0x05400000, followed by the malloc zone. The latter was
bounded by the stack (now client stack), relative to the top of RAM.
An increase of RAM would therefore only enlarge the malloc zone.
Move the malloc zone below the client stack, with a fixed size of 2 MiB.
The size is derived from the memory map depicted in ofmem.c;
having a fixed size leaves room for memory claim'ed by clients

The previous code used the standard set_property() function which copies the new property into the dictionary each time the
property is set. During OpenSolaris boot, this would cause OpenBIOS to run out of memory due to large number of changes to the
memory regions.
Now for each property we have a static buffer allocated within OpenBIOS which starts from 2K and doubles in size everytime the
memory region is exhausted, and set the address directly to the relevant buffer. This saves a great deal of memory and prevents
the dictionary and internal memory regions from being exhausted during OpenSolaris boot.
