      opcodes/arm: add disassembler styling for arm

introduced two places where a register name was passed as the format
string to the disassembler's fprintf_styled_func callback.  This will
cause a warning from some compilers, like this:

  ../../binutils-gdb/opcodes/arm-dis.c: In function ‘print_mve_vld_str_addr’:
  ../../binutils-gdb/opcodes/arm-dis.c:6005:3: error: format not a string literal and no format arguments [-Werror=format-security]
   6005 |   func (stream, dis_style_register, arm_regnames[gpr]);
        |   ^~~~

This commit fixes these by using "%s" as the format string.
