SONIC interrupt handling
Install the built-in macsonic interrupt handler on both IRQs when using
via_alt_mapping. Otherwise the rare interrupt that still comes from the
nubus slot will wedge the nubus.
$ cat /proc/interrupts

auto 3: 744367 sonic
auto 4: 0 scc
auto 6: 318363 via1
auto 7: 0 NMI

Version 1 of this patch had a bug where a nubus sonic card would register
two interrupt handlers. Only a built-in sonic needs both.
Versions 2 and 3 needed some cleanups, as Raylynn Knight and Christoph
Hellwig pointed out (thanks).
