sparc32: Do not select GENERIC_ISA_DMA
[ Upstream commit 99bd9a4f87926e12ce60796d7db1d6b226aca5e3 ]
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]
