[PATCH i-g-t 20/37] lib/igt_fb: Adjust how we pick the blitter compression format

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Instead doing this bpp vs. format thing based on the compression
type, let's stick with the format. In order to avoid having to
populate the table with all the different swizzles we'll pass
the format through igt_reduce_format().
