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.
