sparc32 do not support generic isa dma, so do not select the symbol.

This fixes the following warnings:
dma.c:70:5: error: no previous prototype for 'request_dma' [-Werror=missing-prototypes]
dma.c:88:6: error: no previous prototype for 'free_dma' [-Werror=missing-prototypes]

Fixes: 0fcb70851fbf ("Makefile.extrawarn: turn on missing-prototypes globally")
