Back when the ICU Device Tree binding was introduced, we could not use
mvebu-icu.h from the Device Tree files, because the DT files and
mvebu-icu.h were following different merge routes towards Linus
tree. Now that both have been merged, we can switch the Marvell Armada
CP110 Device Tree files to use the mvebu-icu.h header instead of
duplicating the ICU_GRP_NSR definition.
