Revert "x86/boot: Fail the boot if !M486 and CPUID is missing"
This reverts commit ed68d7e9b9cfb64f3045ffbcb108df03c09a0f98.
The patch wasn't quite correct -- there are non-Intel (and hence
non-486) CPUs that we support that don't have CPUID. Since we no
longer require CPUID for sync_core(), just revert the patch.
I think the relevant CPUs are Geode and Elan, but I'm not sure.
In principle, we should try to do better at identifying CPUID-less
CPUs in early boot, but that's more complicated.
