arm: mvebu: Add DM (driver model) support

This patch adds driver model support for some Marvell MVEBU SoC's. Including
Armada XP and 38x. All 3 currently mainlined boards are converted. DM is now
selected automatically for MVEBU platforms.

With this DM support now available for MVEBU, hardcoding the base addresses
and other information is not necessary any more. Probing should be done
by using the values provided via the device tree now instead. For this
the driver also need to be converted to DM. Patches for some of the drivers
will follow.
