lib/scatterlist: make ARCH_HAS_SG_CHAIN an actual Kconfig
Rather than have architectures #define ARCH_HAS_SG_CHAIN in an
architecture specific scatterlist.h, make it a proper Kconfig option and
use that instead. At same time, remove the header files are are now
mostly useless and just include asm-generic/scatterlist.h.
[sfr@canb.auug.org.au: powerpc files now need asm/dma.h]
