[rtems commit] sparc64: revert linkcmds to 4 MB ram size

[Gedare Bloom]

The niagara BSP does not work with the larger RAM size right now. The
larger size was tested with usiii. I need to eventually split the
linkcmds for the two, because they require different memory layouts.
For now, since niagara is the only BSP that can be tested on open
simulators [1], I will prefer to have the niagara working in the RTEMS
repo. With this patch, and the alignment fix, anyone should be able to
now follow my instructions to get a bootable RTEMS on the GEM5
simulator.
