igvm: acpi: Fix the incorrect CPU count in DSDT table (#51)

Current ACPI tables for CloudHypervisor assumes that there are 4 vcpus
in the system. But that is not the case always and we were seeing
spurious warning emitted by CloudHypervisor during guest boot if the
number of vcpus were less than 4.

cloud-hypervisor: 36.005812s: <vcpu0> WARN:vmm/src/cpu.rs:514 -- Out of range vCPU id: 1
cloud-hypervisor: 36.005982s: <vcpu0> WARN:vmm/src/cpu.rs:514 -- Out of range vCPU id: 2
cloud-hypervisor: 36.006146s: <vcpu0> WARN:vmm/src/cpu.rs:514 -- Out of range vCPU id: 3

The fix is very similar just remove the hardcoded limit of 4vcpus.

igvm: acpi: Update DSDT and MCFG table for 10 segments (#48)

We are not planning to use the complete 96 segments for PCI devices.
Thus, restrict the number of segments 10 in the ACPI tables.

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.
