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.
