I much prefer having seperate, individual IRQs with no requirement on

Now, the L2 binding also doesn't fit too well for the L2CC on Cortex-A15,
which is an inner cache like the one on Cortex-A8. Because of this, it
doesn't have a base address but it *does* have an IRQ which is how external
aborts are raised.
