[PATCH] ipmi: add full sysfs support

Add full driver model support for the IPMI driver.  It links in the proper
bus and device support.

It adds an "ipmi" driver interface that has each BMC discovered by the
driver (as a device).  These BMCs appear in the devices/platform directory.
 If there are multiple interfaces to the same BMC, the driver should
discover this and will only have one BMC entry.  The BMC entry will have
pointers to each interface device that connects to it.

The device information (statistics and config information) has not yet been
ported over to the driver model from proc, that will come later.

This work was based on work by Yani Ioannou.  I basically rewrote it using
that code as a guide, but he still deserves credit :).
