Replace the RISCV_ISA_V dependency of the RISC-V crypto code with RISCV_EFFICIENT_VECTOR_UNALIGNED_ACCESS, which implies RISCV_ISA_V as well as vector unaligned accesses being efficient. This is necessary because this code assumes that vector unaligned accesses are supported and are efficient. (It does so to avoid having to use lots of extra vsetvli instructions to switch the element width back and forth between 8 and either 32 or 64.) This was omitted from the code originally just because the RISC-V kernel support for detecting this feature didn't exist yet. Support has now been added, but it's fragmented into per-CPU runtime detection, a command-line parameter, and a kconfig option. The kconfig option is the only reasonable way to do it, though, so let's just rely on that.
