Daniel Hellstrom 1ca0c808c6 sparc32,leon: Implemented SMP IPIs for LEON CPU 
This patch implements SMP IPIs on LEON using software generated
IRQs to signal between CPUs.

The IPI IRQ number is set by using the ipi_num property in the
device tree, or defaults to 13. LEON SMP systems should reserve
IRQ 13 (and IRQ 15) to Linux in order for the defaults to work.
