PCI: armada: Add driver for Marvell Armada 7K/8K PCIe controller

The Marvell Armada 7K/8K SoCs integrate a PCIe controller from Synopsys.
Add a new driver that provides the small glue needed to use the existing
Designware driver to make it work on Marvell Armada 7K/8K SoCs.

The MSI support will be enabled at a later point.

+          Armada-8K SoCs. The PCIe controller on Armada-8K is based on
+          Designware hardware and therefore the driver re-uses the
