It makes no sense to leave crc32_be using the generic code while we
only accelerate the little-endian ops.
Even though the big-endian form doesn't fit as smoothly into the arm64,
we can speed it up and avoid hitting the D cache.
Tested on Cortex-A53. Without acceleration:
crc32: CRC_LE_BITS = 64, CRC_BE BITS = 64
crc32: self tests passed, processed 225944 bytes in 192240 nsec
crc32c: CRC_LE_BITS = 64
crc32c: self tests passed, processed 112972 bytes in 21360 nsec
With acceleration:
crc32: CRC_LE_BITS = 64, CRC_BE BITS = 64
crc32: self tests passed, processed 225944 bytes in 53480 nsec
crc32c: CRC_LE_BITS = 64
crc32c: self tests passed, processed 112972 bytes in 21480 nsec
