x86/AMD: Remove AMD_ERRATUM_400 definition

AMD_ERRATUM_400 was used to determine whether the processor supports
Always Running APIC Counter (ARAT) feature in init_amd(). Now that
ARAT support is based solely on family number this macro is no longer
needed.

Keep it in comments section as an example in case we ever need to use
it for somethnig else.
