Remove the Niagara stub implementation from sun4u.c and add a machine,
compatible with Legion simulator from the OpenSPARC T1 project.
The machine uses the firmware supplied with the OpenSPARC T1 project,
http://download.oracle.com/technetwork/systems/opensparc/OpenSPARCT1_Arch.1.5.tar.bz2
in the directory S10image/, and is able to boot the supplied Solaris 10 image.
Note that for compatibility with the naming conventions for SPARC machines
the new machine name is lowercase niagara.
