PCI: mvebu: Only remap I/O space if configured
If there is no PCI I/O aperture configured in the Device Tree, it does not make sense to create the virtual mapping for the PCI I/O space, since we will anyway not create the MBus window that will allow to access it. Therefore, do the pci_ioremap_io() only if necessary. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>
