drm/i915: Add .max_stride() plane hook

Browse source

Each plane may have different stride limitations. Let's add a new
plane function to retutn the maximum stride for each plane. There's
going to be some use for this outside the .atomic_check() stuff hence
the separate hook.

v2: Fix ilk+ x-tiled max stride to be 32k (José)
