pci: mvebu: Ensure that root port is always on root zero bus

Writing to the PCI_PRIMARY_BUS register of the root port should not change
bus number on which is root port present.

Same change and exactly same fix as was done in commit for pci-aardvark.c.

Fixes: a7b61ab58d5d ("pci: pci_mvebu: Properly configure and use PCI Bridge (PCIe Root Port)")
