ARM: mvebu: Clean-up the Armada XP support

This patch removes the unneeded include of the armada-370-xp.h header.

It also moves some declarations from this file into more accurate
places.

Finally, it also adds a comment explaining that we can't remove yet the
smp field in the dt machine struct due to backward compatibly of the
device tree.

In a few releases, when the old device tree will be obsolete, we will be
able to remove the smp field and then the armada-370-xp.h header.
