Device tree conversions for samsung and tegra

Both platforms had some initial device tree support, but this adds
 much more to actually make it usable.
 
 This is where the really nasty conflicts in the samsung platform
 start, due to some files getting moved around and combined in the
 'restart' branch that has already gone into mainline through
 Russell's tree.

drivers/tty/serial/Kconfig both due to just adding code close to
changes.
