ARM: vexpress: Remove init_irq declaration in machine description
ARM: vexpress: Remove init_irq declaration in machine description

Commit ebafed7a ("ARM: irq: Call irqchip_init if no init_irq function is
specified") removed the need to explictly setup the init_irq field in
the machine description when using only irqchip_init. Remove that
declaration for vexpress as well.
