In the arm platform, we do not have the "CPU family" as X86.
In the linux kernel, it is hardcode to set the "CPU architecuture:8"
which should be changed for arm v9 in future.
This patch adds "bios_family" field, which we can get from the DMI table.
In the ampere Altra platform, we can get the new lscpu output:
----------------------------------------------------------------
Architecture: aarch64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 160
On-line CPU(s) list: 0-159
Vendor ID: ARM
BIOS Vendor ID: Ampere(R)
Model name: Neoverse-N1
BIOS Model name: Ampere(R) Altra(R) Processor Q00-00 CPU @ 3.0GHz
BIOS CPU family: 257
Model: 1
Thread(s) per core: 1

This patch is just RFC, if it is not proper, we can drop it.
