MIPS: cavium-octeon: fix I/O space setup on non-PCI systems
Fix I/O space setup, so that on non-PCI systems using inb()/outb() won't crash the system. Some drivers may try to probe I/O space and for that purpose we can just allocate some normal memory initially. Drivers trying to reserve a region will fail early as we set the size to 0. If a real I/O space is present, the PCI/PCIe support code will re-adjust the values accordingly. Tested with EdgeRouter Lite by enabling CONFIG_SERIO_I8042 that caused the originally reported crash.
