[IA64-SGI] fix prom revision checks in SN kernel
The following patch fixes two spots in the SN kernel that check a fixed prom revision number to determine prom feature support. These checks are only valid on shub1 systems. They are invalid on shub2 systems which have a different prom with different revision numbers. Signed-off-by: Aaron Young <ayoung@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
