asm-generic: remove ARCH_HAS_SG_CHAIN in scatterlist.h
There are more architectures that don't support ARCH_HAS_SG_CHAIN than those that support it. This removes removes ARCH_HAS_SG_CHAIN in asm-generic/scatterlist.h and lets arhictectures to define it. It's clearer than defining ARCH_HAS_SG_CHAIN asm-generic/scatterlist.h and undefing it in arhictectures that don't support it.
