Merge branch 'remotes/lorenzo/pci/mvebu'

- Implement pci_remap_iospace() for ARM so mvebu can use
  devm_pci_remap_iospace() instead of the previous ARM-specific
  pci_ioremap_io() interface (Pali Rohár)

- Use the standard pci_host_probe() instead of the device-specific
  mvebu_pci_host_probe() (Pali Rohár)

- Replace all uses of ARM-specific pci_ioremap_io() with the
  ARM implementation of the standard pci_remap_iospace() interface and
  remove pci_ioremap_io() (Pali Rohár)

- Skip initializing invalid Root Ports (Pali Rohár)

- Check for errors from pci_bridge_emul_init() (Pali Rohár)

- Ignore any bridges at non-zero function numbers (Pali Rohár)

- Return ~0 data for invalid config read size (Pali Rohár)

- Disallow mapping interrupts on emulated bridges (Pali Rohár)

- Clear Root Port Memory & I/O Space Enable and Bus Master Enable at
  initialization (Pali Rohár)

- Make type bits in Root Port I/O Base register read-only (Pali Rohár)

- Disable Root Port windows when base/limit set to invalid values (Pali
  Rohár)

- Set controller to Root Complex mode (Pali Rohár)

- Set Root Port Class Code to PCI Bridge (Pali Rohár)

- Update emulated Root Port secondary bus numbers to better reflect the
  actual topology (Pali Rohár)

- Add PCI_BRIDGE_CTL_BUS_RESET support to emulated Root Ports so
  pci_reset_secondary_bus() can reset connected devices (Pali Rohár)

- Add PCI_EXP_DEVCTL Error Reporting Enable support to emulated Root Ports
  (Pali Rohár)

- Add PCI_EXP_RTSTA PME Status bit support to emulated Root Ports (Pali
  Rohár)

- Add DEVCAP2, DEVCTL2 and LNKCTL2 support to emulated Root Ports on Armada
  XP and newer devices (Pali Rohár)

- Export mvebu-mbus.c symbols to allow pci-mvebu.c to be a module (Pali
  Rohár)

- Add support for compiling as a module (Pali Rohár)
