media: atomisp: get rid of -Wsuggest-attribute=format warnings 

There are some warnings reported by gcc:
	drivers/staging/media/atomisp//pci/atomisp_compat_css20.c:164:2: warning: function ‘atomisp_css2_dbg_print’ might be a candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format]
	drivers/staging/media/atomisp//pci/atomisp_compat_css20.c:170:2: warning: function ‘atomisp_css2_dbg_ftrace_print’ might be a candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format]
	drivers/staging/media/atomisp//pci/atomisp_compat_css20.c:170:2: warning: function ‘atomisp_css2_dbg_ftrace_print’ might be a candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format]
	drivers/staging/media/atomisp//pci/atomisp_compat_css20.c:176:2: warning: function ‘atomisp_css2_err_print’ might be a candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format]
	drivers/staging/media/atomisp/pci/sh_css.c:1685:16: warning: assignment left-hand side might be a candidate for a format attribute [-Wsuggest-attribute=format]

That are due to the usage of printf-like messages without
enabling the error checking logic.

Add the proper attributes in order to shut up such warnings.
