Consolidate the Poly1305 code into a single module, similar to various other algorithms (SHA-1, SHA-256, SHA-512, etc.): - Each arch now provides a header file lib/crypto/$(SRCARCH)/poly1305.h, replacing lib/crypto/$(SRCARCH)/poly1305*.c. The header defines poly1305_block_init(), poly1305_blocks(), poly1305_emit(), and optionally poly1305_mod_init_arch(). It is included by lib/crypto/poly1305.c, and thus the code gets built into the single libpoly1305 module, with improved inlining in some cases. - Whether arch-optimized Poly1305 is buildable is now controlled centrally by lib/crypto/Kconfig instead of by lib/crypto/$(SRCARCH)/Kconfig. The conditions for enabling it remain the same as before, and it remains enabled by default. (The PPC64 one remains unconditionally disabled due to 'depends on BROKEN'.) - Any additional arch-specific translation units for the optimized Poly1305 code, such as assembly files, are now compiled by lib/crypto/Makefile instead of lib/crypto/$(SRCARCH)/Makefile. A special consideration is needed because the Adiantum code uses the poly1305_core_*() functions directly. For now, just carry forward that approach. This means retaining the CRYPTO_LIB_POLY1305_GENERIC kconfig symbol, and keeping the poly1305_core_*() functions in separate translation units. So it's not quite as streamlined I've done with the other hash functions, but we still get a single libpoly1305 module.
