Ben Dooks fc05c24db0 ARM: orion5x: make orion5x_legacy_handle_irq static
The orion5x_legacy_handle_irq() is not used or declared outside
of irq.c so make it static to avoid the following warning:

arch/arm/mach-orion5x/irq.c:30:23: warning: symbol 'orion5x_legacy_handle_irq' was not declared. Should it be static?
