[PATCH v2 1/3] hw/smbios: code cleanup - use macro definitions for table base addresses

[Ani Sinha]

This is a minor cleanup. Using macro definitions makes the code more
readable. It is at once clear which tables use which starting base addresses.
It also makes it easy to calculate the gaps between the addresses and modify
them if needed.
