[IA64-SGI] sparse cleanups & misc fixes for sn2

This is a big patch mostly because I trimmed shub_mmr.h down from 17M to 11k
or so.  It fixes a number of things sparse discovered and removes some dead
code, fixes up some prototypes, etc.  Of note:
 
o sn_proc_fs.c was directly dereferencing user pointers, fixed
o sn_hwperf.c was missing an include and was using asm-ia64 directly
o the I/O routines were all missing proper sparse annotations
o dead code in prominfo_proc.c has been removed
o fix generic build by putting numionodes into asm/sn/io.h

With this patch applied, the check build is pretty clean.  The sn_console bit
depends on some of the other changes, so it's included here.
