Add some comments, clean up comments over 80 chars per line. There
is an extra line in comment of CPUID_8000_0008_EBX_WBNOINVD, remove
the extra enter and spaces.
Drop the duplicated definition of cpuid AVX512_VBMI macro and rename it
as CPUID_7_0_ECX_AVX512_VBMI. Rename CPUID_7_0_ECX_VBMI2
as CPUID_7_0_ECX_AVX512_VBMI2.
Changelog:
v5:
- correct commit messages. (Suggested by Stefano Garzarella)
v4:
- rename CPUID_7_0_ECX_VBMI2 as CPUID_7_0_ECX_AVX512_VBMI2.
(Suggested by Stefano Garzarella)
v3:
- split the patch into 2 patches. (Suggested by Stefano Garzarella
and Eduardo Habkost)
v2:
- correct the comments over 80 chars per line. (Suggested by
Philippe Mathieu-Daudé)

Drop the duplicated definition of cpuid AVX512_VBMI macro and rename
it as CPUID_7_0_ECX_AVX512_VBMI. Rename CPUID_7_0_ECX_VBMI2 as
CPUID_7_0_ECX_AVX512_VBMI2.
