drm/i915: Set up fb format modifier for initial plane config
drm/i915: Set up fb format modifier for initial plane config

No functional changes yet since intel_framebuffer_init would have
fixed this up for us. But this is prep work to be able to handle new
tiling layouts in the initial plane config code.

Follow-up patches will start to make use of this and switch over to fb
modifiers where needed.
