z2: Make providing flash images non-mandatory 

Up to now, the z2 machine only boots if a flash image is 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.
