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.
