[SPARC64]: Fix system type in /proc/cpuinfo and remove bogus OBP check.
Report 'sun4v' when appropriate in /proc/cpuinfo Remove all the verifications of the OBP version string. Just make sure it's there, and report it raw in the bootup logs and via /proc/cpuinfo. Signed-off-by: David S. Miller <davem@davemloft.net>
