Move the generic implementations from asm-generic/xor.h to per-implementaion .c files in lib/raid. This will build them unconditionally even when an architecture forces a specific implementation, but as we'll need at least one generic version for the static_call optimization later on we'll pay that price. Note that this would cause the second xor_block_8regs instance created by arch/arm/lib/xor-neon.c to be generated instead of discarded as dead code, so add a NO_TEMPLATE symbol to disable it for this case.
