[PATCH] Eval boards should not need to mess with ROOT_DEV

[Grant Likely <grant.likely@secretlab.ca>]

From: Grant Likely <grant.likely@secretlab.ca>

I can't see a good reason for eval board platform code to mess with the
ROOT_DEV value instead of using the default behaviour (so I'm writing
this patch to see if anyone will clue me in).
