acpi: clh: Remove multiple ACPI table for CLH guest (#44)

On the CVM guest kernel side we have figured out a way to unify multiple
IGVMs for different CPU configuration into one. Thus, it is about time
that we can remove multiple directories that we have under acpi-clh for
different CPU configuration and have a single set of ACPI table for CLH
guests.

 ## Cloud Hypervisor support
 We may use the same tool to create IGVM files that [Cloud Hypervisor](https://www.cloudhypervisor.org/) VMM can use to load a confidential guest.
