Right, so we only have use for the native_cpuid_eax() variant right now
but having them all is nicely consistent. They come for almost for free
Also, they're cpuid_<reg>() counterparts and if we don't add the
native_cpuid_e[bcd]x() now I can already see the question: "But but, why
didn't you implement the rest of the CPUID regs?"
Considering how cheap they are, I'd say we keep them all 4.
