The Freescale implementation of the MPIC only allows a single CPU
destination for non-IPI interrupts. Test the flag MPIC_SINGLE_DEST_CPU

This patch adds support for enabling and context switching the Target
Address Register in Power8. The TAR is a new special purpose register
that can be used for computed branches with the bctar[l] (branch
