Support ACPI MCFG multi tables boards for board_inspector

Browse Source 
Some motherboards exposes MCFG1/MCFG2 instead of one ACPI MCFG table,
thus no /sys/firmware/acpi/tables/MCFG exists but MCFG1 and MCFG2.

Read MCFG1 if MCFG doesn't exist.

The same issue report/fix is at https://github.com/intel/pcm/issues/74.

Tracked-On: #8514
