No one uses anything but the default priority.  So let's have a version
of this patch which simplifies this further:

by replacing every instance of the above with a call in their machine
record to at91_init_irq_default(), and:

void __init at91_init_interrupts(unsigned int *priority)
{
	/* Initialize the AIC interrupt controller */
	at91_aic_init(priority);

	/* Enable GPIO interrupts */
	at91_gpio_irq_setup();
}

void __init at91_init_irq_default(void)
{
	at91_init_interrupts(current_soc.default_irq_priority);
}

If people wish to change from the default priority, they can provide
their own init_irq function, and call at91_init_interrupts with their
desired priority array.

btw, this should be const (which should of course be a separate patch).
