powerpc: GE Fanuc's FPGA based PIC controller on the SBC610
Support for the SBC610 VPX Single Board Computer from GE Fanuc (PowerPC MPC8641D).
A number of MPC8641D based route interrupts for on-board interrupts through
a FPGA based interrupt controller, which is chained with the
MPC8641D's mpic. This patch provides a basic driver to allow basic routing
of interrupts to the mpic.
