Do not call pci_set_region() for resources which were not properly mapped. This prevents U-Boot to access unmapped memory space. Update MBUS_PCI_MEM_SIZE and MBUS_PCI_IO_SIZE macros to cover all PCIe MEM and IO ranges. Previously these macros covered only address ranges for the first PCIe port. Between MBUS_PCI_IO_BASE and MBUS_PCI_MEM_BASE there is space for six 128 MB long address ranges. So set MBUS_PCI_MEM_SIZE to value of 6*128 MB. Similarly set MBUS_PCI_IO_SIZE to 6*64 KB. Function resource_size() returns zero when start address is 0 and end address is -1. So set invalid resources to these values to indicate that resource has no mapping. Split global PCIe MEM and IO resources (defined by MBUS_PCI_*_* macros) into PCIe ports in mvebu_pcie_bind() function which allocates per-port based struct mvebu_pcie, instead of using global state variables mvebu_pcie_membase and mvebu_pcie_iobase. This makes pci_mvebu.c driver independent of global static variables (which store the state of allocation) and allows to bind and unbind the driver more times.
