Reorganize the crc-pclmul static_call initialization to place more of the logic in the *_mod_init_arch() functions instead of in the INIT_CRC_PCLMUL macro. This provides the flexibility to do more than a single static_call update for each CPU feature check. Right away, optimize crc64_mod_init_arch() to check the CPU features just once instead of twice, doing both the crc64_msb and crc64_lsb static_call updates together. A later commit will also use this to initialize an additional static_key when crc32_lsb_vpclmul_avx512() is enabled.

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.
