ipmi: support I/O resources in OF driver

Nate Case · torvalds · commit 3b7ec117bf6c · 2008-05-14T19:11:14.000-07:00
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.
