Since sha256_kunit tests the fallback code paths without using crypto_simd_disabled_for_test, make the SHA-256 code just use the underlying may_use_simd() and irq_fpu_usable() functions directly instead of crypto_simd_usable(). This eliminates an unnecessary layer. While doing this, also add likely() annotations, and fix a minor inconsistency where the static keys in the sha256.h files were in a different place than in the corresponding sha1.h and sha512.h files.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
