Thomas Huth c9073238fc hw/audio: Fix crashes when devices are used on ISA bus without DMA
The cs4231a, gus and sb16 sound cards crash QEMU when the user tries
to instantiate them on a machine with DMA-less ISA bus (for example
with "qemu-system-mips64el -M mips -device sb16"). Add proper checks
to the realize functions to avoid the crashes.
