pci: pci_mvebu: set local dev to number 1

Linux displays the real PCIe card connected to a mvebu PCIe slot as
device 0, not 1. This is done by setting local dev number to 1, so that
the local "Marvell Memory controller" device is on address 1.

Let's do it also in U-Boot.

With this commit the pci command in U-Boot prints something like:
  => pci
  Scanning PCI devices on bus 0
  BusDevFun  VendorId   DeviceId   Device Class       Sub-Class
