Use sparc64 version of scatterlist.h.

There are three main differences:
    dma_addr_t replaces __u32
    dma_address replaces dvma_address
    dma_length replaces dvma_length

dma_addr_t is a u32 on sparc32.

Boot tested on sparc32.

Without fancy makefile rules it's not straightforward
to prevent both arch/sparc/kernel/audit.o and lib/audit.o
from both being used on sparc32.

Since arch/sparc/kernel/audit.c is identical to lib/audit.c
except some CONFIG_COMPAT protected sections of code, just
use it on sparc32 too as that's the simplest way to fix
this.
