mips/crc32: expose CRC32 functions through lib

Move the mips CRC32 assembly code into the lib directory and wire it up
to the library interface. This allows it to be used without going
through the crypto API. It remains usable via the crypto API too via
the shash algorithms that use the library interface. Thus all the
arch-specific "shash" code becomes unnecessary and is removed.

Note: to see the diff from arch/mips/crypto/crc32-mips.c to
arch/mips/lib/crc32-mips.c, view this commit with 'git show -M10'.

crypto: mips/poly1305 - enable for all MIPS processors

The MIPS Poly1305 implementation is generic MIPS code written such as to
support down to the original MIPS I and MIPS III ISA for the 32-bit and
64-bit variant respectively. Lift the current limitation then to enable
code for MIPSr1 ISA or newer processors only and have it available for
all MIPS processors.

crypto: mips/poly1305 - incorporate OpenSSL/CRYPTOGAMS optimized implementation

This is a straight import of the OpenSSL/CRYPTOGAMS Poly1305 implementation for
MIPS authored by Andy Polyakov, a prior 64-bit only version of which has been
contributed by him to the OpenSSL project. The file 'poly1305-mips.pl' is taken
straight from this upstream GitHub repository [0] at commit
d22ade312a7af958ec955620b0d241cf42c37feb, and already contains all the changes
required to build it as part of a Linux kernel module.

crypto: mips/chacha - wire up accelerated 32r2 code from Zinc

This integrates the accelerated MIPS 32r2 implementation of ChaCha
into both the API and library interfaces of the kernel crypto stack.

crypto: mips/chacha - wire up accelerated 32r2 code from Zinc

This integrates the accelerated MIPS 32r2 implementation of ChaCha
into both the API and library interfaces of the kernel crypto stack.

The significance of this is that, in addition to becoming available
as an accelerated library implementation, it can also be used by
existing crypto API code such as Adiantum (for block encryption on
ultra low performance cores) or IPsec using chacha20poly1305. These
are use cases that have already opted into using the abstract crypto
API. In order to support Adiantum, the core assembler routine has
been adapted to take the round count as a function argument rather
than hardcoding it to 20.
