df41017eaf ia64: remove support for machvecs
The only thing remaining of the machvecs is a few checks if we are
running on an SGI UV system.  Replace those with the existing
is_uv_system() check that has been rewritten to simply check the
OEM ID directly.

That leaves us with a generic kernel that is as fast as the previous
DIG/ZX1/UV kernels, but can support all hardware.  Support for UV
and the HP SBA IOMMU is now optional based on new config options.

1164e75754 ia64: remove the SGI UV simulator support
The simulator support was marked as temporary since the initial commit,
so drop it more than 10 years later.

cf07cb1ff4 ia64: remove support for the SGI SN2 platform
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.

9726bfcdb9 misc/sgi-xp: remove SGI SN2 support
Note this also marks xp broken on ia64 now, as the UV support, which
was disable in generic kernels before actually never compiled due to
undefined uv_gpa_to_soc_phys_ram and uv_gpa_in_mmr_space symbols since
at least commit c2c9f11574 ("x86: uv: update XPC to handle updated
BIOS interface").
