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.
