pci: pci_mvebu: Move setup for BAR[0] where other BARs are setup

Function mvebu_pcie_setup_wins() sets up all other BARs, so move setup of
BAR[0] to this function to have common code at one place.

In the past, commit 102b3cee3e9b ("pci: pci_mvebu: set BAR0 after memory
space is set") moved setup of BAR[0] to another location, due to ath10k
not working in kernel, but the reason why was unknown, but it seems to
work now, and we think the issue then was cause by the PCIe Root Port
presenting itself as a Memory Controller and therefore U-Boot's code
have overwritten the BAR. Since the driver now ignores any write
operations to PCIe Root Port BARs, this should not be an issue anymore.
