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.

I've applied this to next/fixes-non-critical now. I'm fairly confident that this helps more than it can hurt, but not confident enough to put it into 3.17 or stable for now.
It would be nice to get some testing from someone with hardware access. If necessary, I'll revert the change or do a fixup on top.
