x86: enable VIA CPU support
Newer VIA CPUs have both 64-bit and VMX support. Enable them to be
recognized for these purposes, at once stripping off any 32-bit CPU
only bits from the respective CPU support file, and adding 64-bit ones
found in recent Linux.
This particularly implies untying the VMX == Intel assumption in a few
places.
