irq: add remove_irq() for freeing of setup_irq() irqs
Impact: add new API
This patch adds a remove_irq() function for releasing
interrupts requested with setup_irq().
Without this patch we have no way of releasing such
interrupts since free_irq() today tries to kfree()
the irqaction passed with setup_irq().
