Kevin Hao 04aa99cd0d powerpc/fsl-pci: don't unmap the PCI SoC controller registers in setup_pci_atmu
In patch 34642bbb (powerpc/fsl-pci: Keep PCI SoC controller registers in
pci_controller) we choose to keep the map of the PCI SoC controller
registers. But we missed to delete the unmap in setup_pci_atmu
function. This will cause the following call trace once we access
the PCI SoC controller registers later.
