According to commit 890cc39a8799 ("drivers: provide
devm_platform_get_and_ioremap_resource()"), convert
platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.

Use cpu_to_be32 instead of be32_to_cpu in img_hash_read_result_queue
to silence sparse.  The generated code should be identical.

The assignment to error return variable ret and then the jump to
an error exit path can be simplified by just returning the error
return at the failure point. This allows variable ret and the
error return path to be removed. This cleans up a static analysis
warninng that variable ret is being assigned (value never being
used) and being re-assigned later.

devm_platform_ioremap_resource() and devm_ioremap_resource()
will print err msg while failing, so the redundant dev_err call
can be removed.

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.

The header file algapi.h includes skbuff.h unnecessarily since
all we need is a forward declaration for struct sk_buff.  This
patch removes that inclusion.

Unfortunately skbuff.h pulls in a lot of things and drivers over
the years have come to rely on it so this patch adds a lot of
missing inclusions that result from this.
