The dma_alloc_coherent and dma_free_coherent function seem to be not
available on sparc(32) architecture. It is not used by SBus sound
drivers, so it's disabled via #ifndef for CONFIG_SPARC32.

It is tested on a SparcStation 5 with the cs4231 driver. The ALSA list
should have been CCed, but as it is subscriber-only I skipped it.
