Update family and model detection for AMD CPUs
AMD CPUs uses the similar encoding scheme for extended family and model
as Intel CPUs as shown in:
http://support.amd.com/TechDocs/25481.pdf
This patch updates get_common_indeces to get family and model for both
Intel and AMD CPUs when family == 0x0f.
[BZ #19214]
* sysdeps/x86/cpu-features.c (get_common_indeces): Add an
argument to return extended model. Update family and model
with extended family and model when family == 0x0f.
(init_cpu_features): Updated.
