    riscv: Remove the unused riscv64_cpu driver
    
    This is a repeat of 63bf2d735ca3 ("Remove the unused arm64_cpu driver.")
    for RISC-V, which copied the defunct code from arm64 with no changes
    beyond substituting riscv64 for arm64, and made no use of it elsewhere.
    It has thus always been entirely superfluous.
