[PATCH] ioc4: Enable build on non-SN2

The SGI PCI-RT card, based on the SGI IOC4 chip, will be made available on
Altix XE (x86_64) platforms in the near future.  As such it is now a
misnomer for the IOC4 base device driver to live under drivers/sn, and
would complicate builds for non-SN2.

This patch moves the IOC4 base driver code from drivers/sn to drivers/misc,
and updates the associated Makefiles and Kconfig files to allow building on
non-SN2 configs.  Due to the resulting change in link order, it is now
necessary to use late_initcall() for IOC4 subdriver initialization.

-        This option enables basic support for the IOC4 chip on certain
-        SGI IO controller cards (IO9, IO10, and PCI-RT).  This option
-        does not enable any specific functions on such a card, but provides

-        If you have an SGI Altix with an IOC4-based card say Y.
