drm/i915: Pass drm_format_info into plane->max_stride()

Browse Source 
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.
