Move the powerpc-optimized CRC code from arch/powerpc/lib/crc* into its
new location in lib/crc/powerpc/, and wire it up in the new way. This
new way of organizing the CRC code eliminates the need to artificially
split the code for each CRC variant into separate arch and generic
modules, enabling better inlining and dead code elimination. For more
details, see "lib/crc: Prepare for arch-optimized code in subdirs of
lib/crc/".

Make the architecture-optimized CRC code do its CPU feature checks in
subsys_initcalls instead of arch_initcalls. This makes it consistent
with arch/*/lib/crypto/ and ensures that it runs after initcalls that
possibly could be a prerequisite for kernel-mode FPU, such as x86's
xfd_update_static_branch() and loongarch's init_euen_mask().
Note: as far as I can tell, x86's xfd_update_static_branch() isn't
*actually* needed for kernel-mode FPU. loongarch's init_euen_mask() is
needed to enable save/restore of the vector registers, but loongarch
doesn't yet have any CRC or crypto code that uses vector registers
anyway. Regardless, let's be consistent with arch/*/lib/crypto/ and
robust against any potential future dependency on an arch_initcall.

The use of the term "glue" in filenames is a Crypto API-ism that rarely
shows up elsewhere in lib/ or arch/*/lib/. I think adopting it there
was a mistake. The library just uses standard functions, so the amount
of code that could be considered "glue" is quite small. And while often
the C functions just wrap the assembly functions, there are also cases
like crc32c_arch() in arch/x86/lib/crc32-glue.c that blur the line by
in-lining the actual implementation into the C function. That's not
"glue code", but rather the actual code.
Therefore, let's drop "glue" from the filenames and instead use e.g.
crc32.c instead of crc32-glue.c.
