pci: mvebu: Add PCIe driver

Browse Source 
This adds a PCI driver for the controllers found on Marvell MVEBU SoCs.

Besides the driver, this patch also removes the statically defined
PCI MBUS windows. As they are not needed anymore, since this PCIe
driver now creates the windows dynamically.

Tested on Armada XP db-mv784mp-gp eval board using an Intel E1000
PCIe card in all 3 PCIe slots. And on the Armada 38x db-88f6820-gp
eval board using this Intel E1000 PCIe card in the PCIe 0 slot.

This port was done in cooperation with Anton Schubert.
