Indeed there's no reason to select page size for MMUv2 (read ARC 750D), but
IMHO it's good to let user know what's current page size.

Because software built for ARC 750D will run perfectly fine on ARC770D
if it has the same page size (and by default it is 8k).

That's why I decided to leave a "Page Size" entry in configuration utility
even though it could not be modified for ARC 750D.
