mvebu: add inital support for Marvell Armada XP/370 SoCs

This brings in the initial support for the Marvell Armada XP/370 SoCs.
Successfully tested on RD-A370-A1 and DB-MV784MP-GP boards the following
interfaces:

- Ethernet
- SDIO
- GPIOs
- SATA

+The SDIO interface is available either on pins MPP9/11/12/13/14/15 or
+MPP47/48/49/50/51/52 on the Armada 370. Even though all combinations
+are potentially possible, those two muxing options are the most
+probable ones, so we provide those at the SoC level .dtsi file.
+
+In practice, in turns out the Armada 370 DB board uses the former,
+while the Armada 370 Mirabox uses the latter.
