dmanegine: idxd: reformat opcap output to match bitmap_parse() input
To make input and output consistent and prepping for the per WQ operation configuration support, change the output of opcap display to match the input that is expected by bitmap_parse() helper function. The output will be a bitmap with field width as the number of bits using the %*pb format specifier for printk() family.
