lscpu: show the number of physical socket on aarch64 machine without ACPI PPTT
Show the number of the number of physical socket even if the sysfs doesn't
have the physical socket information.
Note, lscpu shows the number of physical socket as 'Socket(s):' only if
root user runs it because accessing the DMI table requires root
privilege.
