crypto: lib/poly1305 - remove INTERNAL symbol and selection of CRYPTO
Now that the architecture-optimized Poly1305 kconfig symbols are defined
regardless of CRYPTO, there is no need for CRYPTO_LIB_POLY1305 to select
CRYPTO. So, remove that. This makes the indirection through the
CRYPTO_LIB_POLY1305_INTERNAL symbol unnecessary, so get rid of that and
just use CRYPTO_LIB_POLY1305 directly. Finally, make the fallback to
the generic implementation use a default value instead of a select; this
makes it consistent with how the arch-optimized code gets enabled and
also with how CRYPTO_LIB_BLAKE2S_GENERIC gets enabled.

crypto: x86 - drop redundant dependencies on X86
arch/x86/crypto/Kconfig is sourced only when CONFIG_X86=y, so there is
no need for the symbols defined inside it to depend on X86.
In the case of CRYPTO_TWOFISH_586 and CRYPTO_TWOFISH_X86_64, the
dependency was actually on '(X86 || UML_X86)', which suggests that these
two symbols were intended to be available under user-mode Linux as well.
Yet, again these symbols were defined only when CONFIG_X86=y, so that
was not the case. Just remove this redundant dependency.

As these functions are no longer indirectly called (i.e., have their
address taken), the compiler will not emit __kcfi_typeid symbols for
them but SYM_TYPED_FUNC_START expects these to exist at link time.
Switch the definitions of these functions to use SYM_FUNC_START, as they
no longer need kCFI type information since they are only called
directly.

crypto: shash - Handle partial blocks in API
Provide an option to handle the partial blocks in the shash API.
Almost every hash algorithm has a block size and are only able
to hash partial blocks on finalisation.
Rather than duplicating the partial block handling many times,
add this functionality to the shash API.
It is optional (e.g., hmac would never need this by relying on
the partial block handling of the underlying hash), and to enable
it set the bit CRYPTO_AHASH_ALG_BLOCK_ONLY.
The export format is always that of the underlying hash export,
plus the partial block buffer, followed by a single-byte for the
partial block length.
Set the bit CRYPTO_AHASH_ALG_FINAL_NONZERO to withhold an extra
byte in the partial block. This will come in handy when this
is extended to ahash where hardware often can't deal with a
zero-length final.
It will also be used for algorithms requiring an extra block for
finalisation (e.g., cmac).
As an optimisation, set the bit CRYPTO_AHASH_ALG_FINUP_MAX if
the algorithm wishes to get as much data as possible instead of
just the last partial block.
The descriptor will be zeroed after finalisation.
