[Why] VM_helper needs to be intialized with the dc struct in order to fix an unallocated memory issue. System aperture settings should be initialized to 0 and guarded with a check to make sure vm_config is valid. [How] Allocate and free memory for vm_helper with other dc members. Check whether the vm_config valid bit is set before initializing aperture settings.
