What if user wants root from other place? What if mmc number changes,
which is actually happening all the time (hint: use partuuid)? Drop
root, it's not that helpful.
You also do not need console, so drop entire bootargs.

No underscores in node names. Generic node names, so at least generic
prefix or suffix. Anyway you should override your properties via
phandle/label style.
