PCI: mvebu: Propagate errors when updating PCI_IO_BASE and PCI_MEM_BASE registers

Properly propagate failure from mvebu_pcie_add_windows() function back to
the caller mvebu_pci_bridge_emul_base_conf_write() and correctly updates
PCI_IO_BASE, PCI_MEM_BASE and PCI_IO_BASE_UPPER16 registers on error.
On error set base value higher than limit value which indicates that
address range is disabled. When IO is unsupported then let IO registers
zeroed as required by PCIe base specification.
