ARM: dts: ux500: Add Codina TMO device tree

This adds a device tree for "Codina TMO" also known as
Samsung Galaxy Exhibit or Samsung SGH-T599. It is quite different
from the vanilla Codina despite sharing the same board file in
the vendor tree.

Fix up some comments in the Codina DTS while we're at it.
