[PATCH] IPMI: reserve I/O ports separately

From: Corey Minyard <minyard@acm.org>

This patch is pretty important to get in for IPMI, new systems have been
changing the way ACPI and IPMI interact, and this works around the problems
for now.  This is a temporary fix until we get proper ACPI handling in
IPMI.

Fixed releasing already-allocated regions when a later request fails, and
forward-ported it to HEAD.

Some BIOSes reserve disjoint I/O regions in their ACPI tables for the IPMI
controller.  This causes problems when trying to register the entire I/O
region.  Therefore we must register each I/O port separately.
