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.
