FUJITA Tomonori 204f3a0444 asm-generic: remove ISA_DMA_THRESHOLD in scatterlist.h

This is the first half of the attempt to use asm-generic/scatterlist.h
on every architecture.

There are only two ways to define scatterlist structure. So it's easy
to convert every architecture to use asm-generic/scatterlist.h.

This patch:

The trick for ISA_DMA_THRESHOLD in asm-generic/scatterlist.h doesn't work
for powerpc.  This lets architectures defin ISA_DMA_THRESHOLD.

Hopefully, we can remove ISA_DMA_THRESHOLD in the future; we can do better
to decide if the bouncing is necessary or not.
