Pass the format info into plane->max_stride() from the caller instead of doing yet another drm_format_info() lookup on the spot. drm_format_info() is both rather expensive, and technically incorrect since it doesn't return the correct format info for compressed formats (though that doesn't actually matter for the current .max_stride() implementations since they are just interested in the cpp value). Most callers already have the format info available. The only exception is intel_dumb_fb_max_stride() where we shall use the actually correct drm_get_format_info() variant.
