Christoph Hellwig c46928fdcf xor: move generic implementations out of asm-generic/xor.h

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.
