    hdac: Defer interrupt allocation in hdac_attach()

    hdac_attach() registers an interrupt handler before allocating various
    driver resources which are accessed by the interrupt handler.  On some
    platforms we observe what appear to be spurious interrupts upon a cold
    boot, resulting in panics.

    Partially work around the problem by deferring irq allocation until
    after other resources are allocated.  I think this is not a complete
    solution, but is correct and sufficient to work around the problems
    reported in the PR.
