dmanegine: idxd: reformat opcap output to match bitmap_parse() input

[ Upstream commit a8563a33

 ]

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.
