This solution would move all the sn2 initializaions into the
device_initcall sequence.  Which might cause some ordering
problems.  E.g. sn_pci_init() is a "subsys_initcall" ... and I
expect that it really needs to happen before any of the

So there would have to be a sn_* version for potentially each of
the 7 existing levels of initcall to keep the ordering.
