dm: refine logic to build ACPI table of Post-launched VM

Browse Source 
- GET_PLATFORM_INFO will not be supported in ACRN.
  - This patch removes the dependency on this interface
    to build virtual ACPI table of post-launched VM:
      Instead of calling 'vm_get_config()' to get local
      APIC IDs, virtual ACPI builder calls new wrapper API
      'lapcid_from_pcpuid()'.
