Eric Biggers 511484fa88 riscv/crc64: add Zbc optimized CRC64 functions
Wire up crc64_be_arch() and crc64_nvme_arch() for 64-bit RISC-V using
crc-clmul-template.h.  This greatly improves the performance of these
CRCs on Zbc-capable CPUs in 64-bit kernels.

These optimized CRC64 functions are not yet supported in 32-bit kernels,
since crc-clmul-template.h assumes that the CRC fits in an unsigned
long.  That implementation limitation could be addressed, but it would
add a fair bit of complexity, so it has been omitted for now.
