    RISC-V: Fix two ARI warnings.
    
    > gdb/riscv-tdep.c:1657: code: %ll: Do not use printf(%ll), instead use printf(%s,phex()) to dump a 'long long' value
    gdb/riscv-tdep.c:1657:                  "Writing %lld-byte nop instruction to %s: %s\n",
    > gdb/riscv-tdep.c:1658: code: long long: Do not use 'long long', instead use LONGEST
    gdb/riscv-tdep.c:1658:                  ((unsigned long long) sizeof (nop_insn)),
    
    fprintf_unfiltered doesn't support z (or j for that matter), and fixing that
    is a larger patch than I'd like to write, so this does basically what the
    ARI warnings recommends.  We don't need the cast as there is a prototype for
    plongest.
    
            * riscv-tdep.c (riscv_push_dummy_code): Change %lld to %s and use
            plongest instead of unsigned long long cast.
