There's bits of this like logging the top level error interrupts that
seem like they clearly fit in the driver for the top level chip (SYSCLK
possibly in the audio driver, dunno if it gets used by other functions),
they're users of the interrupt controller rather than part of the
interrupt controller.

Isn't that just a data difference which could be parameterised?
