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
and by OpenBIOS.

rather than below the stack. Adjust and prettify the illustration.

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.
