Drop 'inline' from all the *_mod_init_arch() functions so that the
compiler will warn about any bugs where they are unused due to not being
wired up properly. (There are no such bugs currently, so this just
establishes a more robust convention for the future. Of course, these
functions also tend to get inlined anyway, regardless of the keyword.)

Since crc_kunit now tests the fallback code paths without using
crypto_simd_disabled_for_test, make the CRC code just use the underlying
may_use_simd() and irq_fpu_usable() functions directly instead of
crypto_simd_usable(). This eliminates an unnecessary layer.
Take the opportunity to add likely() and unlikely() annotations as well.

Move the powerpc-optimized CRC code from arch/powerpc/lib/crc* into its
new location in lib/crc/powerpc/, and wire it up in the new way. This
new way of organizing the CRC code eliminates the need to artificially
split the code for each CRC variant into separate arch and generic
modules, enabling better inlining and dead code elimination. For more
details, see "lib/crc: Prepare for arch-optimized code in subdirs of
lib/crc/".
