PATCH 1/1 clk: Use __printf markup to silence compiler

Silence warnings (triggered at W=1) by adding relevant __printf attributes.

drivers/clk/clkdev.c:267:3: warning: function might be possible candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format] drivers/clk/clkdev.c:280:2: warning: function might be possible candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format] drivers/clk/clkdev.c:398:2: warning: function might be possible candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format]
