Blackfin: update tiny board settings (voltage/default env)
The tinyboards like to run at a little lower voltage than the default, and they prefer to boot over the network. For the latter, extend the common code a little to make this easier. Also fix the cm-bf527 env sector size while we're in here to reflect the flash that is actually in use.
