Previously we use unified vm_config.c for all scenarios and use MACROs for each configuration items, then the initialization of vm_configs[] becomes more complicated when definition of MACROs increase, so change the coding style that all configurable items could be explicitly shown in vm_configuration.c to make code more readable.
