x86: Use __get_cpu_features to get cpu_features
Remove is_intel, is_amd and max_cpuid macros. Use __get_cpu_features
to get cpu_features instead.
* sysdeps/x86/cacheinfo.c (is_intel): Removed.
(is_amd): Likewise.
(max_cpuid): Likewise.
(__cache_sysconf): Use __get_cpu_features to get cpu_features.
(init_cacheinfo): Likewise.
