pci: pci_mvebu: set BAR0 after memory space is set
The non-DM version of this driver used to set BAR0 register after the
calls to pci_set_region.
I found out that for some strange reason the ath10k driver in kernel
fails to work if this is done the other way around.
I know that Linux's driver should not depend on how U-Boot does things,
but for some strange reason it does and this seems to be the simplest
solution. Fix it since it caused regressions on Omnia.
