Fix the following warning:
insn-automata.c: In function ‘int maximal_insn_latency(rtx_insn*)’:
insn-automata.c:679:37: warning: array subscript -1 is below array bounds of ‘const unsigned char [19]’ [-Warray-bounds]
  679 |   return default_latencies[insn_code];
      |          ~~~~~~~~~~~~~~~~~~~~~~~~~~~^
insn-automata.c:397:30: note: while referencing ‘default_latencies’
  397 |   static const unsigned char default_latencies[] =
      |

Tested and pushed.

gcc/
	* config/csky/csky_pipeline_ck802.md : Use insn reservation name
	instead of *.
