ARM: cns3xxx: Add support for PCI Express ports

This patch adds PCIe support for CNS3xxx-based boards. The support was tested with a directly attached SKY2 NIC, and EHCI USB controller behind the PLX PEX8112 P2P bridge (to make sure that type1 cfg cycles work as expected). Signed-off-by: Anton Vorontsov <avorontsov@mvista.com>
