Continue disentangling the crypto library functions from the generic
crypto infrastructure by moving the powerpc ChaCha and Poly1305 library
functions into a new directory arch/powerpc/lib/crypto/ that does not
depend on CRYPTO. This mirrors the distinction between crypto/ and
lib/crypto/.

Though the module_exit functions are now no-ops, they should still be
defined, since otherwise the modules become unremovable.

Following the example of the crc32, crc32c, and chacha code, make the
crypto subsystem register both generic and architecture-optimized
poly1305 shash algorithms, both implemented on top of the appropriate
library functions. This eliminates the need for every architecture to
implement the same shash glue code.
Note that the poly1305 shash requires that the key be prepended to the
data, which differs from the library functions where the key is simply a
parameter to poly1305_init(). Previously this was handled at a fairly
low level, polluting the library code with shash-specific code.
Reorganize things so that the shash code handles this quirk itself.
Also, to register the architecture-optimized shashes only when
architecture-optimized code is actually being used, add a function
poly1305_is_arch_optimized() and make each arch implement it. Change
each architecture's Poly1305 module_init function to arch_initcall so
that the CPU feature detection is guaranteed to run before
poly1305_is_arch_optimized() gets called by crypto/poly1305.c. (In
cases where poly1305_is_arch_optimized() just returns true
unconditionally, using arch_initcall is not strictly needed, but it's
still good to be consistent across architectures.)

Currently the Power10 optimized Poly1305 is only wired up to the
crypto_shash API, which makes it unavailable to users of the library
API. The crypto_shash API for Poly1305 is going to change to be
implemented on top of the library API, so the library API needs to be
supported. And of course it's needed anyway to serve the library users.
Therefore, change the Power10 optimized Poly1305 code to implement the
library API instead of the crypto_shash API.

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.
