Previously we were setting an illegal configuration on mpc85xx
MPICs if CONFIG_IRQ_ALL_CPUS is enabled (which for some reason it is
in mpc85xx_smp_defconfig).

Sigh, please ignore the repost of this and the CONFIG_IRQ_ALL_CPUs  
patch -- there were some leftover patches in my directory that I didn't  
notice when running git send-email to send the coreint patches.

Don't ignore the original posting of these patches, though. :-)
