Subject: ipmi: check, if default ports are accessible on PPC

From: Christian Krafft <krafft@de.ibm.com>

ipmi_si_intf tries to access default ports, if no device could
be found elsewhere. On PPC we have a function to check,
if these legacy IO ports are accessible. This patch adds
a check for these ports on PPC.
This patch fixes a breakage of IPMI module
on PPC machines without a BMC.
