[PATCH v2 0/5] Marvell EBU PCIe driver

Second round of the Marvell EBU PCIe driver patch set. Compared
to v1, I reworked pci_scan_bus to properly set IORESOURCE flags
for all resources, and added auto-incrementing pci bus numbering.

Patch 1 is unchanged and still fixes resource computation of mbus
driver. Patch 2 now properly sets IORESOURCE flags for I/O, 32b
MEM, and 64b MEM resources.

Patch 3 is a squashed and reworked patch dealing with pci host
controller registration: bus number is now assigned from an auto-
incremented bus_index and already provided pci_controller's
set_busno is called right before pci_scan_bus to allow the
controller to update internal registers related with bus number.
This patch also sets a back-reference to the pci_controller of
a pci_bus and cleans up some unused left-overs from Linux import.

Patch 4 is unchanged import of of_pci_get_devfn() and Patch 5
finally adds the PCIe controller driver for Marvell MVEBU SoCs.
Individual changelogs are also at the corresponding patch mails.

Again, this has been tested on Armada 370 Mirabox.

I added Lucas's Acked-by to all individual patches except new
Patch 3, although I did not respect his request for
'#if defined(FOO)' removal in MVEBU PCIe driver.
