ia64: remove support for the SGI SN2 platform

Browse Source 
The SGI SN2 (early Altix) is a very non-standard IA64 platform that was
at the very high end of even IA64 hardware, and has been discontinued
a long time ago.  Remove it because there no upstream users left, and it
has magic hooks all over the kernel.
