IPMI: Add PPC openfirmware unregister
When trying to load the ipmi_si module on a powerpc with no BMC (baseboard
management controller) the driver failes to load correctly, but doesn't
unregister itself from of_platform. So, on a second modprobe the kernel
crashes. This patch adds the missing unregister call.
