ARM: cns3xxx: fix allmodconfig panic in pci driver
The kernel panic occurs when running an allmodconfig kernel on OMAP4460. The inicall "cns3xxx_pcie_init" does not check which hardware it's running on and just tries to access to its specific registers. Now call it from .init_late callback from the two machine descriptors.
