[PATCH] mainstone: Make providing flash images non-mandatory

[Guenter Roeck <linux@roeck-us.net>]

Up to now, the mainstone machine only boots if two flash images are
provided. This is not really necessary; the machine can boot from initrd
or from SD without it. At the same time, having to provide dummy flash
images is a nuisance and does not add any real value. Make it optional.
