crypto: arm64/crc32 - remove PMULL based CRC32 driver
Now that the scalar fallbacks have been moved out of this driver into the core crc32()/crc32c() routines, we are left with a CRC32 crypto API driver for arm64 that is based only on 64x64 polynomial multiplication, which is an optional instruction in the ARMv8 architecture, and is less and less likely to be available on cores that do not also implement the CRC32 instructions, given that those are mandatory in the architecture as of ARMv8.1. Since the scalar instructions do not require the special handling that SIMD instructions do, and since they turn out to be considerably faster on some cores (Cortex-A53) as well, there is really no point in keeping this code around so let's just remove it.
