[PATCH] IPMI: Allow hot system interface remove
This modifies the IPMI driver so that a lower-level interface can be
dynamically removed while in use so it can support hot-removal of hardware.
It also adds the ability to specify and dynamically change the IPMI interface
the watchdog timer and the poweroff code use.
