crypto: stm32 - Revert broken pm_runtime_resume_and_get changes

[ Upstream commit 3d6b661330a7954d8136df98160d525eb04dcd6a ]

We should not call pm_runtime_resume_and_get where the reference
count is expected to be incremented unconditionally. This patch
reverts these calls to the original unconditional get_sync call.

crypto: sha - split sha.h into sha1.h and sha2.h

Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2,
and <crypto/sha3.h> contains declarations for SHA-3.

This organization is inconsistent, but more importantly SHA-1 is no
longer considered to be cryptographically secure. So to the extent
possible, SHA-1 shouldn't be grouped together with any of the other SHA
versions, and usage of it should be phased out.

Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and
<crypto/sha2.h>, and make everyone explicitly specify whether they want
the declarations for SHA-1, SHA-2, or both.

This avoids making the SHA-1 declarations visible to files that don't
want anything to do with SHA-1. It also prepares for potentially moving
sha1.h into a new insecure/ or dangerous/ directory.

crypto: stm32 - Fix sparse warnings

This patch fixes most of the sparse endianness warnings in stm32.
The patch itself doesn't change anything apart from markings,
but there is some questionable code in stm32_cryp_check_ctr_counter.

That function operates on the counters as if they're in CPU order,
however, they're then written out as big-endian. This looks like
a genuine bug. Therefore I've left that warning alone until
someone can confirm that this really does work as intended on
little-endian.

crypto: ahash - remove useless setting of type flags

Many ahash algorithms set .cra_flags = CRYPTO_ALG_TYPE_AHASH. But this
is redundant with the C structure type ('struct ahash_alg'), and
crypto_register_ahash() already sets the type flag automatically,
clearing any type flag that was already there. Apparently the useless
assignment has just been copy+pasted around.

So, remove the useless assignment from all the ahash algorithms.

This patch shouldn't change any actual behavior.

treewide: kmalloc() -> kmalloc_array()

The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:

kmalloc(a * b, gfp)

with:
kmalloc_array(a * b, gfp)

as well as handling cases of:

kmalloc(a * b * c, gfp)

with:

kmalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

kmalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

kmalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The tools/ directory was manually excluded, since it has its own
implementation of kmalloc().

The Coccinelle script used for this was:
