[PATCH] IPMI: Support I/O resources in OF driver

[Corey Minyard]

From: Nate Case <ncase@xxxxxxxxxxx>

The current OF probing assumes that the resource is IORESOURCE_MEM.
This checks for the IORESOURCE_IO flag and behaves appropriately.
An I/O resource can exist with an ipmi device node on a legacy ISA bus.

Seems reasonable to me, though I have no way to test this. -corey
