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.
