Instead of exposing the arm-optimized SHA-1 code via arm-specific
crypto_shash algorithms, instead just implement the sha1_blocks()
library function.  This is much simpler, it makes the SHA-1 library
functions be arm-optimized, and it fixes the longstanding issue where
the arm-optimized SHA-1 code was disabled by default.  SHA-1 still
remains available through crypto_shash, but individual architectures no
longer need to handle it.

To match sha1_blocks(), change the type of the nblocks parameter of the
assembly functions from int to size_t.  The assembly functions actually
already treated it as size_t.

Instead of exposing the arm-optimized SHA-512 code via arm-specific

library function.  This is much simpler, it makes the SHA-512 (and
SHA-384) library functions be arm-optimized, and it fixes the
longstanding issue where the arm-optimized SHA-512 code was disabled by

I get a very rare -Wstringop-overread warning with gcc-15 for one function

This could happen in theory if walk.nbytes is larger than INT_MAX and gets
converted to a negative local variable.

Keep the type unsigned like the orignal nbytes to be sure there is no
integer overflow.

This reverts commit c4741b23059794bd99beef0f700103b0d983b3fd.

Crypto API self-tests no longer run at registration time and now
occur either at late_initcall or upon the first use.

Therefore the premise of the above commit no longer exists.  Revert
it and subsequent additions of subsys_initcall and arch_initcall.

Note that lib/crypto calls will stay at subsys_initcall (or rather
downgraded from arch_initcall) because they may need to occur
before Crypto API registration.

Instead of providing crypto_shash algorithms for the arch-optimized
SHA-256 code, instead implement the SHA-256 library.  This is much
simpler, it makes the SHA-256 library functions be arch-optimized, and
it fixes the longstanding issue where the arch-optimized SHA-256 was
disabled by default.  SHA-256 still remains available through
crypto_shash, but individual architectures no longer need to handle it.

To merge the scalar, NEON, and CE code all into one module cleanly, add
!CPU_V7M as a direct dependency of the CE code.  Previously, !CPU_V7M
was only a direct dependency of the scalar and NEON code.  The result is
still the same because CPU_V7M implies !KERNEL_MODE_NEON, so !CPU_V7M
was already an indirect dependency of the CE code.

To match sha256_blocks_arch(), change the type of the nblocks parameter
of the assembly functions from int to size_t.  The assembly functions
actually already treated it as size_t.

While renaming the assembly files, also fix the naming quirk where
"sha2" meant sha256.  (SHA-512 is also part of SHA-2.)

Continue disentangling the crypto library functions from the generic
crypto infrastructure by moving the arm BLAKE2s, ChaCha, and Poly1305
library functions into a new directory arch/arm/lib/crypto/ that does
not depend on CRYPTO.  This mirrors the distinction between crypto/ and
lib/crypto/.
