Currently, pflash devices can be configured only via -pflash or -drive options. This is the legacy way and the better way is to use -blockdev as in other architectures. libvirt also has moved to use -blockdev method. To support -blockdev option, pflash devices need to be created in instance_init itself. So, update the code to move the virt_flash_create() to instance_init. Also, use standard interfaces to detect whether pflash0 is configured or not.
