drm/{i915, xe}/panic: drop dependency on struct intel_framebuffer

Store tiling function pointer in struct intel_panic instead of struct
intel_framebuffer, and store struct intel_panic pointer instead of
struct intel_framebuffer pointer in struct drm_scanout_buffer private
member.

To make this happen, pass the tiling function pointer to panic setup
hook, and initialize sb->private in the hook for clarity.

This allows us to drop the dependency on struct intel_framebuffer from
i915 and xe panic code.

Note: It would be less verbose to have a typedef for the tiling function
pointer. However, there isn't a nice location for it that wouldn't also
increase header interdependencies.
