Zide Chen 5420b34a26 hv: provide vm_config information in get_platform_info hypercall 
Hypervisor reports VM configuration information to SOS which can be used to
dynamically allocate VCPU affinity.

Servise OS can get the vm_configs in this order:

1. call platform_info HC (set vm_configs_addr with 0) to get max_vms and
   vm_config_entry_size.
2. allocate memory for acrn_vm_config array based on the number of VMs
   and entry size that just got in step 1.
3. call platform_info HC again to collect VM configurations.
