 * INTERRUPT SOURCE register
 * This is kind of odd on the MPC8240.  The interrupts are kind of
 * spread around.
 *	* The 5 external interrupts are at 0x10200 + irq * 0x20
 *	* The next 3 interrupts are at 0x11000 + (irq - 4) * 0x20
 *	* The next interrupt is at 0x110C0 + (irq - 4) * 0x20
 *	* The last interrupts are at 0x01120 + (irq - 9) * 0x40
