    lantiq: lzma-loader: fix mismatched function declaration
    
    This fix compilation warning:
    printf.c:14:13: warning: type of 'board_putc' does not match original declaration [-Wlto-type-mismatch]
       14 | extern void board_putc(int ch);
          |             ^
    board-lantiq.c:24:6: note: type mismatch in parameter 1
       24 | void board_putc(char c)
          |      ^
    board-lantiq.c:24:6: note: type 'char' should match type 'int'
    board-lantiq.c:24:6: note: 'board_putc' was previously declared here
