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

+From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
+
+When mv_xor_channel_add() fails for one XOR channel, we jump to the
+err_channel_add label to clean up all previous channels that had been
+initialized correctly. Unfortunately, while handling this error
+condition, we were disposing the IRQ mapping before calling
+mv_xor_channel_remove() (which does the free_irq()), which is
+incorrect.
+
+Instead, do things properly in the reverse order of the
+initialization: first remove the XOR channel (so that free_irq() is
+done), and then dispose the IRQ mapping.
+
+This avoids ugly warnings when for some reason one of the XOR channel
+fails to initialize.
