Section numbering has been updated, and there doesn't seem to be a stable
link to a specific version of the doc, recommend to refer to table name instead?
Table 1-2. "Information Returned by CPUID Instruction"


> The following CPU flags are added in this patch:
>     - AVX-512 doubleword and quadword instructions.
>     - AVX-512 integer fused multiply-add instructions.
>     - AVX-512 conflict detection instructions.
>     - AVX-512 byte and word instructions.
>     - AVX-512 vector length instructions.
>     - AVX-512 vector bit manipulation instructions.
>     - AVX-512 vector bit manipulation 2 instructions.
>     - Galois field new instructions.
>     - Vector AES instructions.
>     - Vector carry-less multiply instructions.
>     - AVX-512 vector neural network instructions.
>     - AVX-512 for bit algorithm instructions.
>     - AVX-512 vector popcount instructions.
>     - Cache line demote instructions.
>     - Direct store instructions.
>     - Direct store 64B instructions.
>     - AVX-512 two register intersection instructions.

Required a git am --3way due to some file movements in master, but applied
cleanly on auto-merge.

Add a VNNI documentation line wrap on new line:
RTE_CPU_FLAG_AVX512VNNI,
/**< AVX512 Vector ...  */

With the above changes/updates;
